Answer:
a 32/52 or 8/13
b. 16/52 or 4/13
c. 1/1
d. 28/52 or 7/13
e. 38/52 or 19/26
Step-by-step explanation:
You can count all the even cards of the 52, or just note that there are four suits (hearts, diamonds, clubs, spades), each equally likely, with 13 cards. 5 of those 13 have even numbers (2, 4, 6, 8, 10), four have odd (3, 5, 7, 9), there are 3 "face" cards (jack, queen, king), and the ace. The face cards are usually taken to have value 10, as in blackjack, and the ace is a 1 (or 11), so ONE answer to the question is that 8 of the 13 cards are even: 2, 4, 6, 8, 10, J, Q, K. So, the final answer is 32/52 or 8/13
