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

1        50      50       50      105       50       50      105

2        19       50      64       104       20       32       52

b) MC for first unit = 45

c) ATC of 3rd unit = 63
