Question

A particular fruit's weights are normally distributed, with a mean of 406 grams and a standard deviation of 9 grams.

If you pick one fruit at random, what is the probability that it will weigh between 379 grams and 394 grams

Answer 1

P(379<X<394) = 0.0899 = 8.99%

Explanation:

P(379<X<394) = normalcdf(379,394,406,9) = 0.0898613146 ≅ 8.99%

Therefore, if you pick one fruit at random, the probability that it will weigh between 379 grams and 394 grams is 0.0899 or about an 8.99% chance of occurence.
