What is the probability that a student will not choose a sandwich for lunch? Represent your answer as a percent rounded to the nearest tenth.

Question

mac n chesee-5

sandwich-8

soup-6

hamburger-2

chicken nuggets 1

Answer 1

ASSUMING, the choices for lunch are RANDOMLY selected, then there are 22 possible choices for lunch and 8 are "sandwiches" although I might be tempted to call hamburgers also a sandwich but I'll just keep it simple..

So the probability of selecting a sandwich is 8/22 and that makes the probability of NOT selecting a sandwich at 14/22 which is 63.6%
