Answer:
1/10
Step-by-step explanation:
There are two numbers less than 3 (1 and 2), and one number greater than 4 (5).
When the first slip is drawn, there are five slips in the hat, so the probability of a number less than 3 is 2/5.
When the second slip is drawn, there are four slips in the hat, so the probability of a number greater than 4 is 1/4.
Therefore, the total probability is (2/5) (1/4) = 1/10
