1.	What is the probability of drawing a King or a Queen or a Jack from a deck of cards?
Answer» 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 = \(\frac{n(A)}{n(S)}=\frac{4}{52}\) Probability of drawing a Queen card = \(\frac{n(B)}{n(S)}=\frac{4}{52}\) Probability of drawing a Jack card = \(\frac{n(C)}{n(S)}=\frac{4}{52}\) The Probability of drawing a King or a Queen or a Jack from a deck of cards = P(A) + P(B) + P(C) = \(\frac{4}{52}+\frac{4}{52}+\frac{4}{52}=\frac{4+4+4}{52}=\frac{12}{52}=\frac{3}{13}\)

What is the probability of drawing a King or a Queen or a Jack from a deck of cards?

Answer»

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

= \(\frac{n(A)}{n(S)}=\frac{4}{52}\)

Probability of drawing a Queen card

= \(\frac{n(B)}{n(S)}=\frac{4}{52}\)

Probability of drawing a Jack card

= \(\frac{n(C)}{n(S)}=\frac{4}{52}\)

The Probability of drawing a King or a Queen or a Jack from a deck of cards

= P(A) + P(B) + P(C) = \(\frac{4}{52}+\frac{4}{52}+\frac{4}{52}=\frac{4+4+4}{52}=\frac{12}{52}=\frac{3}{13}\)
