So since 2/3 of Spinner 1 is sedans (The 3rd is a truck), and 1/2 of Spinner 2 is purple (the other half is a green), write a multipilcation problem to describe the probability of spinning a purple sedan.

Write a problem to describe the probability of spinning a purple truck.

  1. looks like a probab of (2/3)(1/2) or 1/3 for spinning a purple sedan

    NOT spinning a green truck?

    First calculate the prob of a green truck
    = (1/3(1/2) = 1/6

    so prob of NOT a green truck = 1 - 1/6 = 5/6
