Five cards—ten, jack, queen, king, and an ace of diamonds are shuffled face downwards.One card is picked at random If a king is drawn first and put aside, what is the probability that the second card picked up is the ace?
उत्तर
Total no. of possible outcomes = 5 {5 cards}
When king is drawn and put aside, total no. of remaining cards = 4
Total no. of possible outcomes = 4
E ⟶ event of drawing ace card
No. favourable outcomes = 1 {1 ace card}
P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`
P(E) =1/4
