Answer:
probability is 4 / 13
Explanation:
Total number of cards in a standard deck = 52 cards.
total number of diamonds = 13 cards
total number of queens = 4 cards.
We should remember that in 13 cards of diamonds there is one queen. so total diamonds and queens are = 13 + 3 = 16 cards
The probability that Jack picked a diamond or a queen
= 16 / 52 = 4 / 13
