<PRE><B>Question 947096</B>
In a standard deck, there are:
13 spades 
4 aces
26 red cards
You also have to account for double counting,
The ace of spades (spade)
The ace of hearts (red)
The ace of diamonds (red)
So then,
{{{P=(13+4+26-3)/52}}}
{{{P=40/52}}}
{{{P=10/13}}}
.
.
.
You could also look at the cards that are left and work backwards.
It would be all the clubs minus the ace of clubs which would be 12 cards.
{{{N=(52-12)/52=40/52=10/13}}}
