From a barrel of colored marbles you randomly select 7 blue, 5 yellow, 8 red, 4 green, and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is either green or purple. Write your answer in simplest form.
Accepted Solution
A:
Green is 4 and Purple is 6 so you put it in a fraction by adding all of them and the just green and purple so 10/30 simplified is 1/3.
