    Thiese are similar to the problem you posted in the Honework Help forum - have you tried working on those? See: https://www.askmehelpdesk.com/middle...ty-778522.html

    Your answer to (a) is correct, but none of the others are correct. As with your other post you need to use the fact that the probability of two independent events occuring in succession is equal to the probability of the first times the probability of the second. So for part (b) the probability of losing two games in a row is 0.8^2 = 0.64. You had an answer of 1, but that would mean he could never win both games, which is intuitively not right. Try these problems again and repost with yuor answers.
