Question

A jar contains 6 red marbles, 7 green marbles, and 2 blue marbles. What is the probability the marble chosen at random will be green

Answer 1

Answer: 7/15

Step-by-step explanation:

1. Most probability questions are asking to find the favourable outcomes over the number of total outcomes.

The favourable outcomes will be green marbles.

There are 7 green marbles, so there are seven favourable outcomes.

There 6 + 7 + 2 = 15 total outcomes.

Thus, there are 7/15 favourable outcomes.
