Explanation:

total marbles = 100

yellow marbles = 28

purple marbles = 11

orange marbles = 32

red marbles = 16

blue marbles = 13

A.

drawing a red marble or a purple marble = 16/100 + 11/100 = 27/100

B.

drawing an orange marble or a purple marble = 32/100 + 11/100

= 43/100

C.

drawing a yellow marble, an orange marble or a blue marble =

28/100 + 32/100 + 13/100 = 73/100

D.

drawing a red marble, a yellow marble, or a blue marble =

16/100 + 28/100 + 13/100 = 57/100

E.

drawing a red marble or an orange marble =

16/100 + 32/100 = 48/100 = 12/25
