Hi,
game that costs $5.00 to play. <u>Two coins are tossed</u>.
You get $10.00 if two heads appear. You get $5.00 if one head appears. 
You get nothing if there are no heads.
               2-Heads       1-Head        2-Tails
 {{{E[v] = 5*(1/2)(1/2) + 0*(1/2)(1/2) - 5*(1/2)(1/2))}}} = {{{5/4-5/4 = 0}}}
Game is a fair game
