Probability and statistics question.

You can order food from Jimmy John's with a mean delivery time of 15 minutes with and a standard deviation of 5 minutes, or you can order from Angie's subs with a mean delivery time of 17 minutes with a standard deviation of 4 minutes. You want your pizza delivered within 14 minutes of ordering.

What is the probability of each sub shop delivering your food within 14 minutes?
