PROBABILITY PLZ HELP:(

Question

CONSIDER A REGULAR DECK OF CARDS WITHOUT THE JOKERS. CARDS ARE REPLACED AFTER EACH DRAW. FIND THE PROBABILITY OF EACH OF THE FOLLOWING.

 

P(pair of kings)

P(a diamond and an eight)

 

USE THE SAME DECK OF CARDS BUT DO NOT REPLACE THE CARD ACTER EACH DRAW.

 

P( four of spades and King of diamonds)

P( a king and a queen)

Answer 1

P(K,K) = (4/52) *(4/52) = 1/169

 

P(D, 8) = (13/52) * (4/52) = 1/52

 

 

P(4S, KD) = (1/52)*(1/51) = 1/2652   NOTE: denominator must decrease since there is one less card in the deck.

 

P(K, Q) = (4/52) * (4/51) = 4/663
