Back to 6.3 Estimating the Binomial with the Normal Distribution

6.3 Exercise 2

Avg difficulty 2.5

Let’s assume that only 10% of the wooden furniture made by a carpenter is made to the exact dimensions in the blueprint. During the last 3 years, the carpenter has made 100 pieces of wooden furniture, and 16 were found to be made to the exact dimensions in the blueprint.

What is the probability that, in 100 wooden furniture items, more than 16 would be made to the exact dimensions of the blueprint?
