Solution

The correct option is C 12

Suppose, E is an event of drawing a red card from a well-suffled pack of 52 cards.

As there are 52 cards in the deck, total number of possible outcomes= total number of available cards= 52.

And, as there are two red suits (diamonds, hearts) with 13 cards each, the total number of red cards= 2×13=26.

Number of favorable outcomes of the event E= number of red cards in the pack of 52 cards= 26

Hence,

P (E)=Number of favourable outcomesTotal number of possible outcomes

P (E)=Number of red cardsTotal number of cards

P (E)=2652=262×26=12

The probability of drawing a red card from a well-suffled pack of 52 cards is 12.
