Suppose the first trial has probability of success 0.2, and the second is successful with probability 0

Question:

Suppose the first trial has probability of success 0.2, and the second is successful with probability 0 if the first is and succeeds with probability 0.25 if the first fails. Show that the second trial has a probability 0.2 of success. Find the probabilities of zero, one, and two successes, and compare with the binomial with n = 2 and p = 0.2.
The binomial depends on two key assumptions: the trials must each have the same probability of success, and the trials must be independent. Show that the of outcomes does not match the binomial in the following cases.
