Asked: September 11, 2026In: Class 9 Maths

A teacher mixes a large bag of sweets of different colours and randomly selects a sample of 30 sweets. She counts the number of sweets of each colour: 10 red sweets | 8 green sweets | 7 yellow sweets | 5 blue sweets (i) Calculate the probability that a randomly picked sweet from the sample is green. (ii) If there are 600 sweets in total in the large bag, estimate how many are likely to be yellow, based on the sample results.

For green sweets, probability is 8 / 30 = 4 / 15 (or approximately 0.267). For yellow sweets, sample probability is 7 / 30. In 600 sweets, the expected yellow sweets count is (7 / 30) x 600 = 140.
