Question

A girl has 7 green apples and 6 red apples in a bag. she picks one apple at rondom. Draw a tree diagram to illustrate all the possible outcome? what is the probability that the first apple eaten was green?​

Answer 1

well there isn't much to draw for a tree diagram since the only possible outcomes are to pick 1/7 green apples or 1/6 red apples.

however, the probability that the first apple eaten was green is 7/13

Explanation:

there are 7 green apples and 6+7=13 total apples, so the probability is:
(total number of desired outcomes)/(total number of possible outcomes)

which is 7/13
