Question

StatTutor: Independence and the multiplication rule A bent coin has probability 0.55 of landing heads up. What is the probability that five tosses of the coin will result in at least one heads? Use four decimal places in your answer.

Answer 1

Answer:

0.9815

Step-by-step explanation:

P(head) = 0.55

P(tail) = 1 - 0.55 = 0.45

P(Atleast one head)

= 1 - P(all tails)

= 1 - 0.45⁵

= 0.9815471875

= 0.9815
