767. Find the probability of drawing a king, when a card is drawn from a well shuffled pack of cards. It is also given that the card drawn is a face card.


Number of cards = 52
Number of kings = 5
Number of face cards = 16
Let E denote the event of drawing a king and F the even of drawing face card.
therefore space space space space straight P left parenthesis straight E right parenthesis space equals space 4 over 52 comma space space space straight P left parenthesis straight F right parenthesis space equals space 16 over 52
straight P left parenthesis straight E intersection straight F right parenthesis space equals space 4 over 52
Required probability  = P(E/F) = fraction numerator straight P left parenthesis straight E intersection straight F right parenthesis over denominator straight F end fraction space equals fraction numerator begin display style 4 over 52 end style over denominator begin display style 16 over 52 end style end fraction space equals 1 fourth
