A coin is tossed 20 times. A person, who claims to have extrasensory perception, is asked to predict the outcome of each flip in
1 answer:
The experiment could be considered as a Bernoulli trial, modeled by the Binomial distribution.
n = 20, number of trials
p = 1/2, the probability of success
q = 1-p = 1/2, probability of failure
The probability of at least 14 successes in 20 trial is
P(success>=14) = ₂₀C₁₄ p¹⁴ q²⁰⁻¹⁴
= 0.037
Answer: 0.037
