Dear Student
i) the probability that a card is a diamond
We know that there are 13 diamond cards in a deck.
Therefore, the required probability is:
P( getting a diamond card) = 13/52
= ¼
(ii) the probability that a card is not an ace
We know that there are 4 ace cards in a deck.
Therefore, the required probability is:
P(not getting an ace card) = 1-( 4/52)
= 1- (1/13)
=(13-1)/13
= 12/13
(iii) the probability that a card is a black card
We know that there are26 black cards in a deck.
Therefore, the required probability is:
P(getting a black card) = 26/52 = ½
(iv) the probability that a card is not a diamond
We know that there are 13 diamond cards in a deck.
We know that the probability of getting a diamond card is 1/4
Therefore, the required probability is:
P( not getting a diamond card) = 1- (1/4)
= (4-1)/4
= ¾
