Question
One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting a face card.
Solution
Total number of cards in a well-shuffled deck = 52
Total number of face cards = 12
P (getting a face card) = `"Number of favourable outcomes"/"Total number of outcomes"`
= `12/52`
= `3/13`
