Question

A box contains 5 strawberry chocolates, 6 coffee chocolates and 2 peppermint chocolates. If one of the chocolates is picked from the box at random, find the probability of the following events by completing the activity.

Activity : Let ‘S’ is the sample space.

∴ n(S) = 5 + 6 + 2 = 13

Event B: it is a peppermint chocolate.

∴ n(B) = `square`

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

P(B) = `square/13`

Answer 1

Let ‘S’ be the sample space.

∴ n(S) = 5 + 6 + 2 = 13

Event B: it is a peppermint chocolate.

∴ n(B) = 2

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

P(B) =  `2/13`
