Question

Two questions to answer…

A bag of uninflated balloons contains 5 red, 9 blue, 16 yellow, and 8 green balloons. A balloon is drawn at random. Find each probability.

1: What is the probability of picking a balloon that is not yellow?

2: What is the probability of picking a balloon that is not red?

PLEASE HURRY!! TYSMMM!!!

Answer 1

Answers:

1. probability = 11/19
2. probability = 33/38

===================================================

Explanations:

1. There are 5+9+16+8 = 38 balloons and 16 of them are yellow. So 38-16 = 22 are not yellow. This leads to 22/38 = 11/19 being the probability of picking something that isn't yellow.
2. Same idea as problem 1. This time we don't want red. There are 5 red so there are 38-5 = 33 non-red balloons. We end up with the answer 33/38

For either problem, you could find the decimal form, but I think the fraction form is better (since it's exact instead of approximate).
