Question

There are 30 marbles in a bag. There are 10 red marbles, 7 green, 6 blue, and 7 yellow. If you randomly grab a single marble, what are the odds of grabbing a yellow?

Select the correct answer below:


23:7
7:23
7:30
23:30

Answer 1

• C) 7 : 30

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

The odds means the probability or a chance.

We have 30 total and 7 yellow marbles.

The probability of grabbing a yellow is:

• P(yellow) = number of yellow / total number
• P(yellow) = 7/30

This is matching the third choice or C) 7 : 30.
