Step-by-step explanation:

The question is not properly formatted, here is how it should be formatted.

A bag contains 6red jelly beans, 4 green jelly beans, and 4 blue jelly beans. If we choose a jelly bean, then another jelly bean without putting the first one back in the bag, what is the probability that the first jelly bean will be green and the second will be red

Step one

This is selection without replacement.

Sample space

6red jelly beans,

4 green jelly beans, and

4 blue jelly beans.

S = 6+4+4 = 14

Probability that the first jelly bean will be green = 4/14 = 2/7

Without replacement, Probability that the second jelly bean will be red = 6/13

Hence for the two selections the probability is = 2/7*6/13 = 12/91
