Need help with expected value?

Letting X be the amount won, we have:

E(X) = ∑X.p(X)

i.e. (1/8)[1 + 2 + 5 + 6 + 8 + 10 + (-17) + (-17)]

Note: -17 is a loss of $17

so, (1/8)(-2) => -0.25

Interpreting this we can say her expected win is -$0.25 per game

or, a loss of $0.25 per game

-0.25 (with a negative sign) is her expected gain.

The question asks what will she "lose"

She will lose 0.25 (without the minus sign)
