The probability of him drawing a marble that is not red?
A.1/4
B.1/2
C.3/4
D.1

Answer:
C
Step-by-step explanation:
Add all the marbles, you get 20.
count the number of non-red marbles, you get 15.
Now to find probability, you want a fraction, or a percentage, so either way, you write 15/20.
which simplified is 3/4
