Question

A package of 36 petunia seeds contains 10 seeds for red flowers, 8 seeds for white flowers, and 18 seeds for purple flowers. Three seeds are randomly selected and planted. Find the probability that the first seed will produce a purple flower, the second seed will produce a white flower, and the third seed will produce a purple flower.

Answer 1

For the first selection, we have \(18/36\). For the second selection we have \(8/35\). For the third \(17/34\).

Answer 2

This is because the total number of seeds goes down.

Answer 3

That's why we have \(36,35,34\).

Answer 4

Also by the third drawing, the number of purples went down, so we have \(18,17\).
