Let
be the event "the car stops at the signal.
In the attached figure you can see a tree describing all possible scenarios.
For the first question the red path describes stopping at the first light but not stopping at the second. We can determine the probability of this path happening by multiplying the probabilities on the branches of the tree, thus

For the second one the blue path describes the situation

For the las situation the sum of the two green path will give us the answer

We want to find

, where

is a binomial distribution with

and

. So
