Question

From a pack of 52 cards, a card is chosen at random, find the probability that it is either a king or a jack?

Answer 1

n(A)= 4(of king) +4(of jack)=8

n(S)=52

P(A)=n(A)/n(S)

=8/52

=2/13=>probability

Answer 2

Step-by-step explanation:

$4 \: kings \: and \: 4 \: jacks \: are \: there \: in \: the \\ pack \: of \: 52 \: cards. \\ 4 \: cards + 4 \: cards = 8 \: cards \\ probability = \frac{favourable}{total} = \frac{8 \: cards}{52 \: cards } \\ = \frac{2}{13} \: is \: the \: probability.$
