He diameters of red delicious apples of an orchard have a normal distribution with a mean of 3 inches and a standard deviation of 0.5 inch. one apple will be randomly chosen. what is the probability of picking an apple with diameter between 2.5 and 4.25 inches?

0.8351

Step-by-step explanation:

Given :Mean :

Standard deviation :

The formula for z -score :

For x= 2.5 ,

For x= 4.25 ,

The p-value =

Hence,  the probability of picking an apple with diameter between 2.5 and 4.25 inches =0.8351.

answer: 80,000
