Question
A card is drawn at random from a pack of 52 cards. Find the probability that card drawn is neither an ace nor a king
Solution
E⟶ event of getting neither an ace nor a king.
No. of favourable outcomes = 52 – 4 – 4 = 44 {Since we have 4 aces & 4 kings}
We know that, P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`
P(E) =44/52 =11/13
