Question 448998
There are 6 playing cards placed face down. 
the 4 of diamond , 
the 5 of hearts, 
the 2 of clubs, 
the 10 of spades, 
the 7 of hearts and 
the 3 diamonds. 
A person selects a card , find the expected value of their draw.
-----
The probability of drawing each card is (1/6)
--
Multiply the "value" of each card by its probability.
--
Add the 6 products to get the expected value.
---------
E(x) = (1/6)(4+5+2+10+7+3) = 31/6 = 5.167
