Explanation:
Detailed explanation-1: -The probability of getting an ace is 1/52.
Detailed explanation-2: -1 Expert Answer. In a standard deck of cards there are 52 cards, half of which are red, half are black. Also, there are 4 suits, clubs (♣), diamonds (♦), hearts (♥) and spades (♠), each of which has 13 cards. So the probability of getting a red card is 26/52 = 1/2.
Detailed explanation-3: -The probability of drawing an even card is the total number of even cards divided by the total number of cards. There are 5 even values (2, 4, 6, 8, 10) and 4 of each in the deck. That means there are 20 even cards in a deck of 52 cards. The probability is 20/52.
Detailed explanation-4: -Thus, Probability (getting a black ace) = 522=261.
