Question

A bag contains 3 blue marbles, 8 green marbles, and 4 red marbles. One marble is drawn from the bag. What is the probability that the marble drawn is not blue?

A. 4/5
B. 4
C. 1/5
D. 1/4​

Answer 1

A.4/5

Explanation:

as total outcomes(marbles)=3+8+4=15

P(of getting blue marbles)=3/15

P(not getting blue marbles)= 1-3/15

=(15-3)÷15

=12/15

=4/5
