Question

Two different 2-digit numbers are randomly chosen and multiplied together. What is the probability that the resulting product is even?

Answer 1

Answer:

If the pairs are multiplied together, only the ones with an even number will have an even product. There are 7 of them. They are: 12, 14, 23, 24, 25, 34, and 45. So the probability is 7/10, or 70%.
