Question

1. If you flip a fair coin 5 times, what is the probability of:

(a) Getting all heads?

(b) Getting all tails?

(c) Getting at least one head?

Answer 1

Step-by-step explanation:

P(heads) = ½, and P(tails) = ½

a) P(5 heads) = (½)⁵ = ¹/₃₂

b) P(5 tails) = (½)⁵ = ¹/₃₂

c) P(at least 1 head) = 1 − P(all tails) = ³¹/₃₂
