If 2 cards are selected from a standard deck of 52 cards without replacement, in order to find the probability that both are the same suit, start with the first card...
The probability that the first card is any suit is 52 in 52, or 1.
Now, consider the second card. There are 12 cards remaining in the same suit, and 39 cards remaining in the other three suits...
The probability that the second card is the same suit as the first card is 12 in 51, or 4 in 17, or 0.235.
The probability of both events occurring is the product of those two probabilities. That is still 4 in 17, or 0.235.

The probability of selecting 1 female at random is 4/8 There are now 7 students, 3 of which are female so the probability of selecting another female is 3/7 The probability two randomly selected students are female is (4/8)x(3/7)= 3/14

What is the probability of drawing two aces from a deck of 52 cards?
The answer depends on how many cards are drawn, and whether they are drawn with or without replacement. If 1 card is drawn, the probability is 0, if 50 cards are drawn (without replacement), the probability is 1. If only two cards are drawn, at random and without replacement, the probability is (4/52)*(3/51) = 12/2652 = 0.0045
