उत्तर
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 `4xx10=40`
`"We know that PROBABILITY" = "Number of favourablr event "/"Total number of event"`
`"Hence probability of getting non-faced card "=40/52=10/13`
`"Hence probability of getting a non-face card "=10/13`
