<PRE><B>Question 208098</B>
If the doors can be selected with equal probability,
what is the expected value of the selection if the
three doors have behind them a $40,000 foreign car, a $3
silly straw, and a $50 mathematics textbook?
----------------------------
Random variable values are 40000, 3, and 50
The probability of each is 1/3
-----------------------------
Expected value = (1/3)(40000+3 + 50)
E(x) = (1/3)(40053) = $13,351.00
=========================================
