Question

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 1

Explanation:

To find the probability of Mario randomly selecting a red chip or a white chip, we need to first determine the total number of red and white chips he has.

Total number of red and white chips = 45 + 24 = 69

Therefore, the probability of Mario randomly selecting a red chip or a white chip is:

P(red or white) = (number of red chips + number of white chips) / total number of chips

P(red or white) = (45 + 24) / (45 + 12 + 24)

P(red or white) = 69 / 81

P(red or white) = 0.85

So the probability of Mario randomly selecting a red chip or a white chip is 0.85 or 85%.

Answer 2

Answer: 0.8519 ≈ 85%

Explanation:

To find the probability, we will divide wanted outcomes by total possible outcomes. See below.

`\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{number of red or white chip}}{\text{total number of chips}} =(45+24)/(45+12+24)= (69)/(81)`

= 0.8519 ≈ 85%

The probability that Mario will randomly select a red or white chip is 0.8519 or about 85%.
