In a school garden survey, 300 plants were recorded: 90 roses, 75 marigolds, 60 jasmine and the rest tulsi. A plant is chosen at random. What is the probability that it is either a rose or a tulsi?

Question

Accepted Answer

55/100. Tulsi = 300 - 90 - 75 - 60 = 75. Rose or tulsi = 90 + 75 = 165. P = 165/300 = 55/100 (= 11/20).
