Mario has 45 red chips, 12 blue chips, and 24 white chips. What is the probability that Mario randomly selects a red chip or a white chip?

 

Answer:

23/27

Step-by-step explanation:

45 red chip, 12 blue chips, 24 white chips

45 + 12 + 24 = 81 chips in all

Probability to select a red chip = 45/81 = 5/9

Probability to select a white chip = 24/81 = 8/27

Probability to select a blue chip = 12/81 = 4/27

45 red chip + 24 white chip = 69 red and white chips

Probability to select either a red chip or a while chip = 69/81 = 23/27
