Pat rolled a number cube 60 times. The cube is numbered 1-6. How many times should he expect to roll a multiple of 3?

Answer 1

Answer:

Pat should expect to roll a multiple of 3 20 times.

Step-by-step explanation:

There is a $\frac{2}{6}$ or $\frac{1}{3}$ chance of landing on 3 or 6 every time Pat rolls. That probability doesn't chance.

60 x (1/3) = 20
