What is the probability of drawing a King or a Queen or a Jack from a deck of cards?
उत्तर
Number of cards n(S) = 52
No. of King cards n(A) = 4
No. of Queen cards n(B) = 4
No. of Jack cards n(C) = 4
Probability of drawing a King card
= `("n"("A"))/("n"("S")) = 4/52`
Probability of drawing a Queen card
= `("n"("B"))/("n"("S")) = 4/52`
Probability of drawing a Jack card
= `("n"("C"))/("n"("S")) = 4/52`
The Probability of drawing a King or a Queen or a Jack from a deck of cards
= P(A) + P(B) + P(C)
= `4/52 + 4/52 + 4/52`
= `(4 + 4 + 4)/52`
= `12/52`
= `3/13`
