<PRE><B>Question 947096</B>
A card is drawn from a pack of 52 cards find the probability of getting spade or ace or a red card?
-------
Count the # of ways to succeed::
spade = 13 cards including the ace of spades
red = 26 cards including the ace of hearts and ace of diamonds
ace = 4 cards but 3 are already selected above
----
# of ways to succeed:: (13-1 + 26-2 + 4) = 12+24+4 = 40 
# of possible outcomes:: 52
---
P(spade or red or ace) = 40/52 = 10/13
-------------
