Question

The school provides parking passes that include a letter and a number between 1 and 20. What is the probability that Mr. Welton will be given the parking pass with "W-17" on it?

Answer 1

26 letters in the alphabet.

1-20 = 20 numbers.

The probability of getting w = 1/26

The probability of getting 17 = 1/20

The probability of both: 1/26 x 1/20 = 1/520
