Solution

## The correct option is D 12 Given, Number of red flowers = 7 Number of white flowers = 5 Number of pink flowers = 4 Number of yellow flowers = 8 Total number of flowers in the box = 7 + 5 + 4 + 8 = 24 ⇒ Total number of possible outcomes = 24 Number of favourable outcomes = Number of pink flowers + Number of yellow flowers = 4 + 8 = 12 Probability of an event, P(E) = number of favourable outcomestotal number of outcomes P(picking a pink or yellow flower) = 1224=12 Therefore, the probability that Swetha picks a pink or yellow flower is 12.
