Sam has 15 red pencils, 9 blue pencils, 7 green pencils, 8 pink pencils, and 11 yellow pencils in his bag. How
many times would one expect Sam to pick red pencils if he picked a pencil 90 times?

A) 15
B) 16
C 20
D) 27

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
