<PRE><B>Question 126967</B>
There are 13 diamonds in the deck
If I know that the card is black,
but all the diamonds are red, so there is {{{0}}}
probability that the card is a diamond
-------------------------------
There are 12 picture cards
4 kings
4 queens
4 jacks
so, there are 4 chances in 12 it is a queen
or the probability is 1/3
