Compute the Mean and Standard Deviation of a Hypergeometric Random Variable
-In a lottery, a player must choose 6 numbers between 1 and 36 inclusive. Six balls are then randomly selected from an urn containing 36 balls numbered from 1 to 36 . The random variable XX represents the number of matching numbers. What are the mean and standard deviation of the random variable XX ?


A) μX=1.000,σX=29.580\mu _ { X } = 1.000 , \sigma X = 29.580
B) μX=1.000,σX=0.913\mu \mathrm { X } = 1.000 , \sigma \mathrm { X } = 0.913
C) μX=0.167,σX=29.580\mu _ { X } = 0.167 , \sigma X = 29.580
D) μX=0.167,σX=0.913\mu _ { X } = 0.167 , \sigma X = 0.913
