Question

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?

Answer 1

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
