What is the probability of picking a 5 and then picking a number less than 4?

Write your answer as a percentage.

Answer 1

The probability of picking a 5 on the first draw is 1/5.

Since the card is put back after the first draw, the probability of picking a number less than 4 on the second draw is 2/5.

Therefore, the probability of both events happening is (1/5) * (2/5) = 2/25 = 8%.

So the probability of picking a 5 and then picking a number less than 4 is 8%.
