    hope this helps

    a)You have 1/2 probability of getting an even number and a 1/2 probability of getting an odd number. 2 points for even, -3 points for odd.
    Even= 1/2 x 2
    = 1
    Odd = 1/2 x -3
    = -1.5
    add 1 and /1.5 to get -0.5
    b) Not fair because you will lose more points than win.
