Prob = P(queen) + P(spade) - P(the queen of spades)
= 4/52 + 13/52 - 1/5
= 16/52 = 4/13

The probability that it's a queen would be 1/13, because there are 4 out of 52 cards in the deck that is a queen. 4/52 simplifies to 1/13.
The probability that it's a spade would be 1/4, because there are 13 spades out of the 52 cards in the deck. 13/52 reduces to 1/4.
