Two fair six-sided dice are rolled. What is the probability that the product of the two numbers is a composite number?
Pls answer as a common fraction.
I thought it was 5/6, but it was wrong. Here is my reasoning:
probability the product is NOT composite= rolling 1 on one dice and 2, 3, 5 on the other.
36 different possibilities.
You can roll 1 on dice num. 1 or dice num. 2
