A card is drawn at random from a pack of 52 playing cards. Find the probability of drawing a card that is neither a spade nor a king.
उत्तर
We have a total number of cards 52
And in the deck of 52 cards number of spade are 13
And a number of king = 4
But, out of these 4 kings, 1 king is already included in 13 spades card.
So, we will remove all the spade and king that is `52 - (13 + 3) = 36`
Therefore, the probability of neither a spade nor a king is `36/52 = 9/13`
