Question 449244
A standard deck of cards has four suits: hearts, diamonds, clubs, and spades. Each suit has 13 cards composed of: ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king. Hearts and diamonds are red; clubs and spades are black. If one card is randomly selected,
---------------------------------------------------
a) What is the probability that the card is red, given that the card selected is a heart? 
P(red | heart) = 1
Why?  All hearts are red.
-------------------------------------
b) What is the probability that the card selected is neither an ace nor a jack?
---
P(not ace and not jack)
There are 4 aces and there are 4 jacks
That leaves 44 cards that are not ace and not jack.
Ans: 44/52 = 11/13
