Question

There are 18 marbles in Molly's bag. Two of the marbles are yellow. If Molly chooses one marble at random, find the theoretical probability that she will choose a yellow marble.

Answer 1

1/9

Explanation:

To find this probability, we simply divide the number of yellow marbles by the total number of marbles

From the question, there are a total of 18 marbles and 2 yellow ones

thus, the theoretical probability of selecting a yellow marble will be;

2/18 = 1/9
