Question 411787
A man claims to have extrasensory perception. As a test, a fair coin is flipped 29 times, and the man is asked to predict the outcome in advance. He gets 20 out of 29 correct. What is the probability that he would have done at least this well if he had no ESP?
------
Binomial Problem with n = 29 and p = 1/2
----
P(20<= x <=29) = 1-binomcdf(29,1/2,19) = 0.0307
