उत्तर
Total no. of cards = 52
All jacks, queens and 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 queen
No. of favourable outcomes = 2 {queen of spade and club}
Probability, P(E) =`"No. of favorable outcomes"/"Total no. of possible outcomes"`
P(E) = `2/44`
= `1/22`
