You can put this solution on YOUR website!
Hi,
1)there are 12 face cards(K,Q and J in each of 4 suits) in Deck.
Choose 6(4 face and 2 others), p(4 face cards) =  = = .0190
Saw another posted #860254, no work there as well
Whoa.. if You do not learn HOW to do these..this assignment is not going to
mean much. got You started with 'special ways'...check each out completely...
finding combinations, arithmetic etc
P = special ways/total ways
1)P = special ways/(52C6) = special ways/20,358,520 = =  = .000141
2)33 to chose 9 from
P = special ways/(33C9) = special ways/38567100 =  = .2920147
3) P = special ways/8! =  = .000025 (only 1 way books are alphabetical left to right)
4)32 to chose 14 from
P = special ways/(32C14)= special ways/471,435,600 = 
5) 31 to chose 14 from
P = special ways/(31C14) = special ways/265,182,525 =
You work on the number of Special ways for each
