Ok the probability formula you will want to use is: P=number of desired outcomes/total number of outcomes

Where p is the probability of the desired outcome happening.

In this question the desired outcome is two tails. There is only one way this can happen.

Good. This is because there are only the following outcomes possible. There's: Tails and Tails Tails and Heads Heads and Tails Heads and Heads
