Question

You have a bag with 6 green marbles, 15 blue marbles, 8 red marbles, 1 yellow

marble. What is the probability (as a decimal rounded to three places) of pulling
out a red marble?

Answer 1

0.267 or 26.7%

Explanation:

The probability of an event happening is calculated by dividing the favorable outcomes by all outcomes:

The sum of all events (marbles) is 6 + 15 + 8 + 1 = 30

The number of favorable events is 8

Therefore, the probability is 8/30 ≈ 0.267 or 26.7%
