A nutritionist who investigates fruits reported that the average weight of a raspberry is 4.4 gm with a standard deviation of 1.28 gm. What is the probability that a randomly selected raspberry would weigh less than 3.1 grams?

Let X represent the weight of a randomly selected raspberry. Assume the distribution of weights is approximately normal. Find P( X < 3.1).

Round your answer to two decimal places.
