Grocery Shopping!

Probability Level 2

You are in the middle of grocery shopping and your mom called you asking to get her two items: one box of pasta and one can of tomato sauce. However, she did not mention her favorite product brand. The store has eight brands of pasta and five brands of tomato sauce cans. What is the probability that you might get the two items of her favorite brand?


The answer is 0.025.
