In this problem, it is said that a roulette wheel has 38 slots in which the ball can land.
00:06
Two of them are green, 18 of the slots are red, 18 of them are black, and the ball is equally likely to land in any slot.
00:14
Now, the roulette wheel is going to be spun twice, and the outcomes of the two spins are independent.
00:19
We need to find the probability that it never lands on green.
00:23
So what we need to do is find the probability that it does not land on green.
00:31
Green on the first time the roulette will is spun and it also does not land on green the second time it is spun.
00:40
So here we are considering g1 to be the event that it does not land on green in the first spin and g2 to be the event that it does not land on green in the second spin and intersection represents ads.
00:54
So this is what we get.
00:55
Now it is said that the spins are independent.
00:58
So that means that these two events will be in between...
