Five cards are selected at random without replacement from a standard, thoroughly shuffled 52-card deck of playing cards. Let X equal the number of face cards (kings, queens, jacks) in the hand. Forty observations of X yielded the following data:
2 1 2 1 0 0 1 0 1 1 0 2 0 2 3 0 1 1 0 3
1 2 0 2 0 2 0 1 0 1 1 2 1 0 1 1 2 1 1 0
(a) Argue that the pmf of X is
(b) Draw a
(c) Determine the relative frequencies of 0, 1, 2, 3, and superimpose the relative frequency histogram on your probability histogram.
