A normal distribution has a mean of 10 and a standard deviation of 1. What is the probability of selecting a number that is at most 10? Leave the answer in decimal form to 3 decimal places.

0.500

Step-by-step explanation:

Given : A normal distribution has a mean of 10 and a standard deviation of 1.

Let x be a random variable that represents numbers .

The probability of selecting a number that is at most 10 will be

As the area occupied by standard normal curve less than equal to 0 = 0.500

So, required probability = 0.500

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
