Suppose this coin is flipped four times. Using the binomial formula, find the probability of getting exactly two heads. Example: A fair, six-sided die is rolled 3 times. What is the probability of getting a 5 or greater on exactly two of the rolls? Example: According to the Facts 2006 webpage, 53% of UI students are men and 47% are women. What is the probability that at least 3 of the next 5 students you meet are men?
