Question

There are 20 rabbits, 15 black and 5 white. You take one by one a rabbit. What's the probability of having at least 2 white rabbits next to each other?

Answer 1

`1/20 = .05`

Explanation:

Total = 20 rabbits
probability of getting a white: `P(W) = 5/20 = 1/4`

`P(W,W) = 1/4 * 4/20 = 1/20 = .05`
