Question:
One card is drawn from a well shuffled deck of 52 playing cards. What is the probability of getting a non-face card?
Solution:
GIVEN: One card is drawn from a well shuffled deck of 52 playing cards
TO FIND: Probability of getting a non-face card
Total number of cards are52.
Cards which are non-face are cards of numbers from 1 to 10 of each suit and there are four suits
Total number of non-face cards is 
We know that PROBABILITY = 
Hence probability of getting non-faced card =
Hence probability of getting a non-face card =
