Question

You pick a card at random, put it back, and then pick another card at random.

2 3 4 5

What is the probability of picking a number greater than 3 and then picking a 5?

Answer 1

12.5%

Explanation:

out of the 4 cards only two are >3 (4 and 5)

so 2/4 on the first choice (simplified to 1/2)

picking a 5 is 1/4 since there is only one 5

since they are happening at the same time multiply the two probabilities

1/2*1/4

=1/8

=0.125

=12.5%
