Question

What's the probability of rolling a 2 and then rolling a 5 on two consecutive rolls of a fair six-sided dice?

Answer 1

`1/36`

Explanation:

There is a `1/6` probability of getting a `2` on the first roll and a `1/6` probability of getting a `5` on the second roll.

Since they (rolling a `2` first and rolling a `5` second) are independent events (their probabilities don't affect each other), multiply their individual probabilities to get the probability of both events occurring:

`1/6*1/6=(1*1)/(6*6)=1/36`
