Question

A bag contains 8 blue marbles, 6 green marbles, 12 yellow marbles, and 10 orange marbles. A marble is drawn at random from the bag.
What is the probability that the marble drawn will not be blue?

A.2/9

B.3/4

C.7/9

D.7/8
I was thinking either B or D

Answer 1

Ok, so probablility of not drawing blue

total possible is 8+6+12+10=36

8 are blue so the total of not blue is 36-8=28

so 28 out of 36=28/36=7/9 
the asnwer is 7/9 or C
