Answer:
(a)
The probability that you stop at the fifth flip would be

(b)

, then the expected number of flips needed would be 1/0.5 = 2.
Step-by-step explanation:
(a)
Case 1

Case 2
Imagine that you throw your coin and you get only tails, then you would stop when you get the first head. So the probability that you stop at the fifth flip would be

Therefore the probability that you stop at the fifth flip would be

(b)
The expected numbers of flips needed would be

Therefore, suppose that
, then the expected number of flips needed would be 1/0.5 = 2.
