Two balls are drawn in succession without
replacement from an urn containing 5 orange balls
and 6 violet balls. Let V be the random variable
representing the number of violet balls. Construct
the probability distribution and draw the
histogram.
Suppose three test kits are tested at random.
Let D represent the defective test kit and let N
represent the non-defective test kit. If we let X
be the random variable for the number of
defective test kits, construct the probability
distribution of the random variable X.
