Researchers were interested in whether uniform colors give athletes an advantage. To investigate this question, they considered 457 boxing, tae kwon do, Greco-Roman wrestling, and freestyle wrestling matches in the 2004 Olympic Games, in which the competitors were randomly assigned to wear either red or blue. We can model this situation with a binomial random variableX = number of wins by players wearing red. It turns out that a competitor wearing red won 248 of these matches. If we assume that uniform color has no effect on the competitor’s chances of winning, and that the matches are independent, what is the probability of at least 248 wins for those wearing red in this situation (whenXis binomial)?
