In the Powerball Lottery, 5 different numbers from 1 to 69 are selected. The order they’re selected doesn’t matter. (A 6th number, the red Powerball number is selected from the numbers 1 to 26 but this question only concerns the first 5 numbers selected.) Let X be the number of sets of two consecutive numbers in the 5 selected numbers. For example, X = 1 for 4 − 6 − 18 − 19 − 60 and X = 2 for both 5 − 12 − 13 − 47 − 48 and 5 − 12 − 13 − 14 − 48. The minimum possible value for X is 0, of course, and the maximum is 4. Remember, the order the numbers are drawn doesn’t matter so you will want to sort them a) Calculate E(X) using indicator variables.
