The Author of a Statistics Book Has Trouble Deciding Whether

question 155

Essay

The author of a statistics book has trouble deciding whether to use the words ʺheʺ or ʺsheʺ in the bookʹs
examples. To solve the problem, the author flips a coin each time the problem arises. If a head shows, the
author uses ʺheʺ and if a tail shows, the author uses ʺsheʺ. If this problem occurs 100 times in the book, what is
the probability that ʺsheʺ will be used 58 times?
