1.	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(i) A black queen(ii) A red card(iii) A black jack(iv) A picture card (Jacks, Queens and Kings are picture cards)
Answer» 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} (i) E ⟶ event of getting a black queen No. of favourable outcomes = 2 {queen of spade & club} Probability, P(E) = (No.of favorable outcomes)/(Total no.of possible outcomes) P(E) = 2/44 = 1/22 (ii) E ⟶ event of getting a red card No. of favourable outcomes = 26 – 8 = 18 {total red cards – jacks, queens, kings, aces of red colour} P(E) = 18/44 = 9/22 (iii) E ⟶ event of getting a black jack No. of favourable outcomes = 2 {jack of club & spade} P(E) = 2/44 = 1/22 (iv) E ⟶ event of getting a picture card No. of favourable outcomes = 6 {2 jacks, 2 kings & 2 queens of black colour} P(E) = 6/44 = 3/22

Answer»

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}

(i) E ⟶ event of getting a black queen

No. of favourable outcomes = 2 {queen of spade & club}

Probability, P(E) = (No.of favorable outcomes)/(Total no.of possible outcomes)

P(E) = 2/44 = 1/22

(ii) E ⟶ event of getting a red card

No. of favourable outcomes = 26 – 8 = 18 {total red cards – jacks, queens, kings, aces of red colour}

P(E) = 18/44 = 9/22

(iii) E ⟶ event of getting a black jack

No. of favourable outcomes = 2 {jack of club & spade}

P(E) = 2/44 = 1/22

(iv) E ⟶ event of getting a picture card

No. of favourable outcomes = 6 {2 jacks, 2 kings & 2 queens of black colour}

P(E) = 6/44 = 3/22
