Question

from a well shuffled pack of 52 cards ,a card is drawn at random .find the probability that the card so drawn is king or non faced card .​

Answer 1

Answer:

when a card is drawn from pack of 52 cards then

n(s)=52

n(k)=4

n(f')=52-12=40

n(k intersection f')=4

now,

p(k or f)=p(k)+p(f')-p(k intersection f')

=n(k)/n(s) +n(f')/n(s) -n(k

intersection f')/n(s)

=4/52+40/52-4/52

=40/52

=10/13
