From a pack of 52 playing cards Jacks, queens, kings and aces of red colour are removed. From the remaining, a card is drawn at random. Find the probability that the card drawn is A black jack
उत्तर
Total no. of cards = 52
All jacks, queens & kings, aces of red colour are removed.
Total no. of possible outcomes = 52 – 2 – 2 – 2 – 2 = 44 {remaining cards}
E ⟶ event of getting a black jack
No. of favourable outcomes = 2 {jack of club & spade}
Probability, P(E) = `"No.of favorable outcomes"/"Total no.of possible outcomes"`
P(E) = 2/44 = 1/22
