Since the given event is binary we can use Bernoulli's probability to sove the problem
Thus for an event 'E' with probability of success 'p' the probability that the event occurs 'r' times in 'n' trails is given by
Part a)
For part a n = 11 , r =9, p = 0.75
Applying values we get
Part b)
For part b n = 20 , r = 16 , p=0.75
Applying values we get
