Chapter 0263 Patroller

The first time you choose empty door 1 (probability 1/3), then the host opens another empty door, changes doors, and gets the car. The total probability of the event is 1/3.

The first time you choose empty door 2 (probability 1/3), then the host opens another empty door, changes doors, and gets the car. The total probability of the event is 1/3.

第一次选的汽车（概率1/3）,之后主持人开另一个空门1（概率1/2），不换门，得到汽车这个事件总概率?。

The car is chosen for the first time (probability 1/3), and then the host opens another empty door 2 (probability 1/2). Without changing doors, the total probability of getting the car is ?.

Whether the host chooses to open the empty door No. 1 or the open door No. 2, here is the host's selection probability. I assume that the host chooses randomly (draw lots or at will), so each gives a 50% probability.

If the host just likes open door No. 1 and must open No. 1, then it will become No. 1 (100%) and No. 2 (0%), and the final result will not be affected.

So when you start selecting a car, the probability of not getting a prize is 33.3%. If you start selecting an empty door, the probability of winning a prize after changing doors is 66.6%.

Seeing the reaper getting closer and closer, Zhou Wenwen couldn't hold back and pressed the trigger of the double-barreled shotgun at a distance of a hundred meters. Thunderous gunfire sounded continuously, bang! boom!

Two rounds of No. 2 ammunition propelled by gunpowder split into thousands of marbles in an instant and appeared in front of the reaper.

The Reaper never expected this situation, so before it had time to perform its own emergency stop stunt, the rest of its flight caused it to collide with thousands of marbles, and blood mist flew up in an instant.

Zhou Wenwen is very lucky. The R+G dual virus level 4 zombie advanced mutant reaper in front of him happens to be a type with high attack speed, high damage, high speed, and the lowest defense among zombies.

Especially for Reapers who focus on speed, giving up armor is an inevitable choice, since they are fast anyway.

The injured reaper stagnated in place for three seconds before continuing to fly. By this time, Zhou Wenwen had already left the stairs and corridors and hid in the room.

Although logically speaking, he should have run away directly, but he heard the black man's voice downstairs and was worried that Zhou Wenwen would be attacked from both sides if he went down, so naturally he would not go down.

So Zhou Wenwen had to hide in the room. Fortunately, his plan succeeded.

When the reapers couldn't find Zhou Wenwen, they naturally attacked the black people angrily.

Although the two black men were startled by the sudden appearance of the reapers, they still pressed the triggers of their AR15 rifles and fired a round of 5mm bullets at the reapers.

It seemed that he had learned his lesson after being shot. This time the reaper stopped quickly when he saw the enemy's movement, causing the two black men to empty all their bullets.

The two black men were immediately stunned, and they forgot that the Reaper was around!

When he saw the Reaper's wings vibrating at high speed and was about to fly to deliver a fatal blow to the two black men, Zhou Wenwen, who was watching the show, still could not bear the cost of death as a "human shield" and fired.

Zhou Wenwen calculated the advance accurately and pressed the trigger of the double-barreled shotgun. The thunderous gunshot sounded again, bang! boom!

......

Zhou Wenwen connected the control systems of the six "Ark B1A1" Rangers and the six "Ark CA1" Super Dragoons to the systems on the overclocking armor one by one, and input the data to ensure that the six Rangers and six "Ark CA" Rangers could be remotely controlled. After the Super Dragoon, let the Ranger and Super Dragoon enter the automatic state and throw them out of your hands.

When they escaped from Zhou Wenwen's hands, the six Rangers and the six Super Dragoons were still a little out of control and almost crashed. However, after the safety system began to correct the error, the six Patrollers and the six Super Dragoons entered the state smoothly. , flying towards the target on the ground.

One of the Ranger ultra-clear cameras, labeled No. 3, allowed Zhou Wenwen to see the situation of the female sylph El on the screen.

......

The wind elf El suddenly broke free from his restraints. The six female two-horned and two-winged demons and eighteen male one-horned and wingless demons responsible for performing the blood sacrifice ceremony were shocked, thinking that El wanted to run away.

After all, during the escorting process, several of the female sylphs who accompanied El in the blood sacrifice did so.

Of course, any female sylph who dared to do this would be rewarded by the female double-horned and double-winged devil with a hellhound, first and then as food.

Just when the demons thought that El wanted to run away, they saw that El just made a silent shouting gesture towards the sky. The demons who didn't know this secret skill thought that this guy was just numbed by the rope and wanted to stretch out. The demons who took this into consideration laughed.

The laughter alerted the male wind elf Lille who was sent to guard him and betrayed the wind elf and betrayed his compatriots to join the devil.

Lille, who turned around and saw El's posture, immediately recognized what El's movements meant, and immediately shouted, "She is asking for help from someone high in the sky, stop her!"

Hearing Lear's words, the demons were frightened. They rushed forward, stopped El's movements, and beat El with a whip coated with secret medicine, causing El to faint and wake up from the pain. Come here, repeat this, until El rolls himself up, the demons end the beating.

After the beating was over, when the demons were discussing what to do with the female sylph, Lille, the male sylph who longed for El's body, asked him to come.

Because it was Leal who exposed El's actions, the demons agreed to Leal's actions and let Leal deal with El.

So Lille took off his clothes, revealing his devilish figure, and when he was about to step forward to attack El, Zhou Wenwen, who saw this scene, couldn't help but give the order, action!
