The probability that, in a randomly selected group of r people, at least two people will have the same birthday is given by the following table. What is the probability that, in a group of 25 people, at least one person has a birthday on April 5? Why is your answer different from the probability displayed in the table for r= 25? (Ignore February 29.) r 5 10 15 20 22 23 25 30 40 50 Pr(E) 0.027 0.117 0.253 0.411 0.476 0.507 0.569 0.706 0.891 0.970 The probability that, in a group of 25 people, at least one person has a birthday on April 5 is (Round to three decimal places as needed.)
