Suppose there is a game in which a dice is used. The player earns 20 dollars if face 2 appears, 40 dollars if face 4 appears, and loses 30 dollars if face 6 appears, while he neither loses nor wins if any other face appears. So what is the expectation of the amount that he won and the variation of the game? μ = 6,² =459.3 ( p=5,0²458.3 ( u=8.0²=448.3 (3) c) 462.3= 2,7 = n
