The answer is 1/10. Because there are five cards in all, the chance of drawing a red card is 2/5, and because one of the red cards after drawing it would not be replaced it leaves us with only four cards left and one red card. Therefore, the chance of getting another red card is 1/4. Multiply 2/5 and 1/4 which equals 2/20, and reduce your answer is 1/10.

there are five cards in total, 2 of which a red. that means that the probability of drawing one red card is 2/5.

The probability of then drawing the second red card without replacing the first one is 1/4, because there is now four cards and only one is red.

To get the final answer you multiply both of those together and get 2/20, which is the same as 1/10.

the answer is 1/10
