We can easily find this using equations.  what do we know?

X + Y = 20  and
-(X - Y = 14)        subtract the two equations..

X + Y = 20
-X + y = -14

2Y = 6
Y = 3        (our first number)  (put this into an original equation and solve)

X + Y = 20
X + 3 = 20    subtract 3 from both sides
X = 17

gives us our answer ....... 3 and 17

The expectation value is simply obtained by multiplying the probability of each outcome by each possible value. These are then summed for each outcome to obtain the expectation value. In the board game, if there is a 60% chance that you will move 4 spaces forward (+4) and a 40% chance that you will move back 2 spaces then expected value for number of spaces is (0.6 x 4) + (0.4 x -2) = 2.4 - 0.8 = 1.6 spaces.
