Question

A bag contains 12 green marbles and 9 white marbles. In simplest form, what are the odds in favor of drawing a white marble? A. 4:7 B. 3:4 C. 1:7 D. 4:3

Answer 1

Since we are drawing a white marble, this number goes before any other color in the ratio;

9 white marbles to 12 green marble or 9:12

Simplify the ratio:

9:12

9/3:12/3

3:4

This can't be simplified anymore.

Therefore, the answer is [ B. 3:4 ]

Best of Luck!

Answer 2

3 :4

Explanation:

Remember that odds are different than probability

favor : not in favor ( drawing something other than white)

9 white : 12 not white

Divide each by 3

9/3 : 12/3

3 :4
