Suppose that 5 cards are selected with replacement from a standard deck of 52 playing cards. The deck contains 13 denominations (ace, two, three, … , ten, jack, queen, king) of each of four suits (hearts, diamonds, spades, and clubs). The kings, queens, and jacks are known as face cards.
\n" ); document.write( "---------------------------
\n" ); document.write( "A card is selected and its suit and denomination recorded. The card is replaced in the deck. The deck is shuffled, and the process repeated 4 more times.
\n" ); document.write( "-------------------------------------------------------------------------
\n" ); document.write( "a. What is the probability that all five cards are face cards?
\n" ); document.write( "Since the cards are replaced the selections are independent.
\n" ); document.write( "P(a face card in one draw) = 12/52
\n" ); document.write( "P(5 face cards in 5 draws) = (12/52)^5
\n" ); document.write( "----------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "b. What is the probability that at least one card is a face card?
\n" ); document.write( "P(at least one) = 1 - P(none)
\n" ); document.write( "---
\n" ); document.write( "P(no face card in 5 draws) = (40/52)^5
\n" ); document.write( "P(at least one face card in 5 draws) = 1 - (40/52)^5
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( "c. What is the probability that exactly one card is a face card?
\n" ); document.write( "It's binomial with n= 5 ; p = 12/52, x = 1
\n" ); document.write( "binompdf(5,12/52,1) = 0.4040
\n" ); document.write( "------------------------------------------------
\n" ); document.write( "d. What is the probability that no hearts are selected?
\n" ); document.write( "(3/4)^5
\n" ); document.write( "---------------------------------------------------
\n" ); document.write( "e. What is the probability one or fewer hearts are selected?
\n" ); document.write( "binomial with n=5, p= 3/4, 0<= x <=1
\n" ); document.write( "binomcdf(5,3/4,1) = 0.0156
