Answer:

1/4

Step-by-step explanation:

P(1st head) = heads/ total = 1/2

P (2nd heads) =  heads/ total =1/2

P(3rd heads or tails) =  heads or tails/ total =2/2=1

Since the second flip does not depend on the first flip ( or the third on the first or second) we can just multiply the probabilities

P( head, head, head or tails) = 1/2*1/2*1

                                                 =1/4

Answer:

¼

Step-by-step explanation:

P(H) = ½

P(T) = ½

P(H U T) = 1 (because no other possibility)

½ × ½ × 1

¼
