A card is drawn at random from a well-shuffled deck of playing cards. Find the probability that the card drawn is neither a jack nor a king.
उत्तर
Let S be the sample space of drawing a card from a well-shuffled deck.
`n(S)=""^52C_1=52`
There are 4 jack and 4 king cards in a deck.
So there are 52 -8 = 44 cards which are neither jacks nor kings.
A card which is neither a jack nor a king can be drawn in `""^44C_1=44`
Probability of drawing a card which is neither a jack nor a king=44/52=11/13
