योग

उत्तर

GIVEN: One card is drawn from a well shuffled deck of 52 playing cards

TO FIND: Probability of getting an Ace

Total number of cards are52.

Cards which are Ace are 1 from each suit

Total number of Ace cards is `4xx1=4`

`"We know that PROBABILITY" = "Number of favourable event"/"Total number of event"` 

Hence probability of getting an Ace= `4/52=1/13`

Hence probability of getting an Ace `=1/13`
