Bernardo randomly picks 3 distinct numbers from the set {1, 2, 3, 4, 5, 6, 7, 8, 9} and arranges them in descending order to form a 3-digit number. Silvia randomly

picks 3 distinct numbers from the set {1, 2, 3, 4, 5, 6, 7, 8} and also arranges

them in descending order to form a 3-digit number. What is the probability that

Bernardo’s number is larger than Silvia’s number?

The answer is 37/56.

The problem seems simple but i keep on getting the wrong answer.....
