In the above images answers are given to parts a, b, c, and d of the problem, respectively. I have used probability trees to calculate the probability of each outcome. The paths leading to a given outcome are indicated in red. Probability of a path is calculated by multiplying the individual probabilities on the path. You add the path probabilities to find the probability of each outcome.
