Answer:
Expected value of X = -11.09
Explanation:
Expected profit:
= Probability of winning × Amount she wins
= 0.03 × $180
= 5.4
Expected loss:
= Probability of loosing × Amount she paid
= 0.97 × $17
= 16.49
Let X be amount of money Mary wins or loses.
E(X) = Expected profit - Expected loss
= 5.4 - 16.49
= -11.09
Expected value of X = -11.09
That is expected value of loss of $11.09
