What is the probability a student will choose soup or sandwich for lunch? Represent your answer as a decimal to the nearest hundredth.

Question

mac n chesee-5

sandwich-8

soup-6

hamburger-2

chicken nuggets 1

Answer 1

Total number of choices: 5 + 8 + 6 + 2 +1 = 22

Probability select soup = 6/22

Probability select sandwich = 8/22

Did not mention that you can select soup AND sandwich, so we will assume they are mutually exclusive events (cannot occur at the same time), so probability select soup or sandwich = 6/22 + 8/22 = 14/22 = 7/11 = 0.64.
