##### Reference no: EM131032554

Problem: Choose a common fruit fly Drosophila melanogaster at random. Call the length of the thorax (where the wings and legs attach) Y. The random variable Y has the Normal distribution with mean μ= 0.800 millimeter (mm) and standard deviation μ= 0.078 mm. The probability P(Y > 1) that the fly you choose has a thorax more than 1 mm long is about

(a) 0.995.

(b) 0.5.

(c) 0.005. CH
