Conditional Probability:
Probability of given A in the event of B
Formula: P(a | b)
Example 1:
A card is drawn from a shuffled deck for 52 cards, and not replaced. Then a second card is drawn.
a) What is the probability that the second card drawn is a king?
P( k and k ) + P( K(with line on top) and K)
4/52 x 3/51 + 48/52 x 4/51 = 1/13
