First, we can find the probability that at least two people will roll the same number. The first person can roll any number, and the second person has a 1/6 probability of rolling the same number. The probability that none of the other two people will roll the same number is 5/6 x 4/6 = 10/36. Therefore, the probability that at least two people will roll the same number is:
P(at least two people roll the same number) = 1/6 x 10/36 x 4 = 10/54 = 5/27
Next, we can find the probability that exact
