Question 194851
1)Empirical evidence (on a sample of one) shows that 62/74 or 0.838 of planted bulbs result in flowers. So the 'odds are' 83.8% of planted bulbs flower.
2) How many bulbs are required in order to have 95 that flower? Based on the results on part 1, 83.8% of the planted bulbs flower. You want to have 95 flower, so
{{{NumberPlanted * 0.838 = NumberFlowering}}}
{{{NumberPlanted * 0.838 = 95}}}
{{{NumberPlanted = 113.38}}}
You can't plant 0.38 of a bulb, so you'll want to plant 114 bulbs.

Given that tulips are perennials, and you already have 65 bulbs that flower, the gardners could plant 114 - 65 = 49 more bulbs and get 95 that flower.

But I suspect this problem will want 114 as the answer to part 2.
