In a game of chance, two pyramid-shaped, four-sided dice are rolled and their individual totals are ...

In a game of chance, two pyramid-shaped, four-sided dice are rolled and their individual totals are added. The probability distribution for the game appears in the table.

X	2	3	4	5	6	7	8
P(X=x)	0.0625	0.125	0.1875	0.25	0.1875	0.125	0.0625

If the sum of the two four-sided dice exceeds 5 (result from die 1 + result from die 2 > 5), the roller wins $5 (end result +5). If the sum is 5 or less, the roller loses $3 (end result –3). What is the expected value from this game?
