Answer to Question #329490 in Statistics and Probability for Raaa

Question

Two cards are drawn at random from a set of 52 cards.What is the probability that the both cards are either kings or queens

Answer 1

P(two kings or two queens) = p(2 kings ) + p(2 queens)

$p(2 queens) = (4/52) \cdot (3/51) = 0.0045$

$p(2queens)=(4/52)⋅(3/51)=0.0045$

$0.0045 + 0.0045 = 0.009$
