We know that,
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) Let E = event of getting a black queen
No. of favourable outcomes = 2 (queen of spade & club)
Probability, P(E) = Number of favourable outcomes/ Total number of outcomes
P(E) = 1/22
(ii) Let E = event of getting a red card
No. of favourable outcomes = 26 – 8
= 18 (total red cards jacks – queens, kings, aces of red colour)
Probability, P(E) = Number of favourable outcomes/ Total number of outcomes
P(E) = 18/44 = 9/22
(iii) Let E = event of getting a black jack
No. of favourable outcomes = 2 (jack of club & spade)
Probability, P(E) = Number of favourable outcomes/ Total number of outcomes
P(E) = 2/44 = 1/22
(iv) Let E = event of getting a picture card
No. of favourable outcomes = 6 (2 jacks, 2 kings & 2 queens of black colour)
Probability, P(E) = Number of favourable outcomes/ Total number of outcomes
P(E) = 6/44 = 3/22
