Lottery In the old New York State Lottery, you had to select six numbers between 1 and 54 inclusive. There were 25,827,165 different possible six-number combinations, and you had to select the correct combination of all six numbers to win the grand prize. For a $1 bet, you selected two different six-number combinations. (You could not select a single six-number combination; you had to select two.)

a. If you placed a $1 bet and selected two different six-number combinations, what was the probability of winning the grand prize?

b. Was it unusual to win the grand prize?
