Each person needs to buy at least 3 tickets, because 2 is too small
2(1.50) = 3 and 3(75) = $225
You need $250!
3(1.50) = 4.50 and 4.50(75) = $337.50
It's more than $250, but that's how it would have to be if they each buy an equal amount of tickets
Answer:
a) Computing the expected value E(XY) gives 1/4
b) The probability density function fZ(z) of Z = XY is calculated in the attached picture.
