<PRE><B>Question 327484</B>
Assume that a person spins a pointer and is awarded an amount based on the following: half of the spinner&#39;s area results in winning $8, a quarter of the spinner results in winning $12, and a quarter of the spinner results in winning $1. Determine the person&#39;s expectation.
----
E(x) = (1/2)8 + (1/4)12 + (1/4)1 
---
= 4+3+(1/4) = $7.25 each time the game is played.
