Question

29) 2 cards are drawn from a well shuffled park
of cards. The probability that one card is a
red knave and the other is a black numbered
card is
​

Answer 1

Answer:

5/13

Step-by-step explanation:

let A be the event of getting a red knave

probability of A p(A)= no of red knave / total no of cards

=2 /52

let B be the event of getting a black numbered cards

probability of getting B p(B)= no of black numbered cards/ total no of cards

=18/52

A intersection B= 0. as. black and red cards can't intersect

probability of A intersection B is a null set

probability of drawing ared knave and black numbered cards at the time from a deck of cards is. p(A union B)

= p(A)+p(B)-p(A intersection B)

=2/52+18/52-0

= 20/52

=5/13.
