<PRE><B>Question 187197</B>
A card is selected from a deck of 52 playing cards. Find the probability of selecting 
a) a diamond given the card is black 
Ans: P(diamond AND black)/P(black) = 0/(1/2) = 0
-------------------------------------------------------
b) a queen given the card is a picture card?
Ans: P(q|picture) = P(queen AND picture)/p(picture)= (4/52)/(12/) = 4/12 = 1/3
