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`
