A spinner has 3 three sections, each with different point values and areas.
-The 1-point section is 2/3 the area of the spinner.
-The 2 point section is 1/4 the area of the spinner.
-The 3 point section is 1/12 the area of the spinner.

To the nearest tenth of a point, what is the expected value on any one spin?

1(2/3) + 2(1/4) + 3(1/12) =

8/12 + 6/12 + 3/12 = 17/12

Divide 12 into 17.
