Question

There is a stack of 10 cards, each given a different number from 1 to 10. Suppose we select a card randomly from the stack, replace it, and then randomly select another card. What is the probability that the first card is an even number and the second card is greater than 8?

Write your answer as a fraction in simplest form.

Answer 1

Probability helps us to know the chances of an event occurring. The probability that the first card is an even number and the card is greater than 7 is 0.15.

Explanation:

Probability helps us to know the chances of an event occurring.

The probability that a first card is an even number and the card is greater than 7 is

Probability = (5/10)×(3/10) = 15/100 = 0.15

Hence, the probability that the first card is an even number and the card is greater than 7 is 0.15.
