Question
A card is drawn at random from a pack of 52 cards. Find the probability that card drawn is other than an ace
Solution
E⟶ event of getting card other than an ace.
No. of favourable outcomes = 52 – 4 = 48 {Since we have 4 ace cards}
We know that, P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`
`P(E) =48/52 =12/13`
