Question 1183759: A student takes a true-false test consisting of 10 questions. Assuming the student guesses at each question, find the probability that the student gets a 60% on the test. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This is a binomial problem with n=10 and constant probability of 1/2.
the answer is 10C6*(1/2)^6(1/2)^4=210/1024=0.2051
