Anormal distribution has μ=80 and σ=10. what is the probability of randomly selecting a score greater than 85 from this distribution?

or .

Step-by-step explanation:

We have been given that a normal distribution has μ=80 and σ=10. We are asked to find the the probability of randomly selecting a score greater than 85 from this distribution.

First of all, we will find the z-score corresponding to normal score 85 as:

Upon substituting our given values in z-score formula, we will get:

Now, we need to find for the probability of randomly selecting a score greater than 85 from this distribution.

Using formula , we will get:

Therefore, the probability of randomly selecting a score greater than 85 from this distribution would be 0.30854 or .
