Ms. Crane has a jar with 6 white marblos, 4 red marbles, and 5 blue marbles. If
she closes her eyes and picks one marble out of the jar, what is the probability
that it is not red?
A. 4/15
B. 2/5
C.11/15
D. 2/3
To find probability, you divide whatever you're looking for over your total. In this case, you have 11 marbles that are not red, and 15 marbles total, so your answer would be 11/15.
