a bag contains 9 green marbles and 11 white marbles. you select a marble at random. what are the odds in favor of picking a green marble?

A.) 9:20
B.) 2:9
C.) 11:9
D.) 9:11

if you bet 9 on the green I bet 11 on the white

although the probability of green = 9/20

and the probability of white = 11/20

the ODDS of green are
9/20 / 11/20 = 9/11

To find the odds in favor of picking a green marble, you need to compare the number of favorable outcomes (green marbles) to the number of total outcomes (total number of marbles).

In this case, there are 9 green marbles and 11 white marbles, so the total number of marbles is 9 + 11 = 20.

Therefore, the odds in favor of picking a green marble can be expressed as 9:20.

The correct answer is A) 9:20.
