विकल्प

\[\frac{1}{13}\]
\[\frac{1}{52}\]
\[\frac{12}{13}\]
उत्तर
One card is drawn from a well shuffled deck of 52 playing cards
TO FIND: Probability of getting an Ace
Total number of cards is 52
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 is equal to `4/52=1/13`
