Homework Help: Math

Posted by Punkie on Saturday, November 28, 2009 at 9:26pm.

I was wondering if someone could help me check my work on this problem and see if I'm correct.

Consider the experiment of drawing two cards without replacement from an ordinary deck of 52 playing cards.
What are the odds in favor of drawing a spade and a heart?
There are 52 playing cards in a deck
There are 13 spades and 13 hearts in deck
13 + 13 = 26
P(spade and heart) = 26/52

P(not a spade or heart) = 26/52

Odds in favor of A = Number of ways that A could occur/Number of ways that A could not occur

Odds in favor of A = 26/52 / 1- 26/52 = 0
