Green Purple Yellow

When he was in first grade, Harvey played

Green

games with spinners. One game he especially

liked had two spinners and several markers

Yellow

that you moved around a board. You were

Purple

only allowed to move if your color came up

on both spinners.

a. Harvey always chose purple because that was

his favorite color. What was the probability that

Harvey could move his marker?

b.

Is the probability that Harvey moves his marker

calculated from a union or an intersection of

events?

c.

Was purple the best color choice? Explain.

d.

If both spinners are spun, what is the probability

that no one gets to move because the two colors

are not the same?

e.

There are at least two ways to calculate the answer to part (d). What is

another way to solve?
