Question

A card is drawn from a well shuffled pack of 52 playing cards. Find the probability of the event, the card drawn is a red card.

Activity: Let ‘S’ be the sample space.

∴ n(S) = 52

Event A: Card drawn is a red card.

∴ Total red cards = `square` hearts + 13 diamonds

∴ n(A) = `square`

∴ P(A) = `square/(n("S"))`    ......[Formula]

P(A) = `26/52`

P(A) = `square`

Answer 1

Let ‘S’ be the sample space.

∴ n(S) = 52

Event A: Card drawn is a red card.

∴ Total red cards = 13 hearts + 13 diamonds

∴ n(A) = 26

∴ P(A) = `bb(n(A))/(n(S))`    ......[Formula]

P(A) = `26/52`

P(A) = `bb(1/2)`
