P(not green or orange)

Postby nycmath » Thu Sep 10, 2026 10:41 am

A gum ball machine contains gum balls of five different colors: 36 red, 44 white, 15 blue, 20 green, and 5 orange. The machine dispenser randomly selects one gum ball. What is the probability that the gum ball selected is not green or orange?

@ Eigenvalue,

I guess you are going to solve every question and not leave some to do another day.
