You pick a card at random, put it back, and then pick another card at random.
6
7
8
9
What is the probability of picking a number less than 8 and then picking a 7?
Write your answer as a percentage.
The probability of picking a number less than 8 is 3/4 (since there are 3 out of 4 cards that are less than 8). The probability of picking a 7 after that is 1/4 (since there is only 1 card that is a 7). To find the probability of both events happening together, we multiply the probabilities: (3/4) * (1/4) = 3/16.
To write this as a percentage, we multiply by 100: (3/16) * 100 = 18.75%.
Therefore, the probability of picking a number less than 8 and then picking a 7 is 18.75%.
