with regard to question 1, if one card is lost from a deck, and
5 cards are drawn, all clubs, what is the probability that the
lost card was a club:

after 5 cards are drawn, there are 46 left.
P(lost card is club)= 1-P(lost card is not club)=1-((13*3)/46)=7/46
this isn't =.1702, as P. Koch claims. where did i err?
