a normal distribution has a mean of 10 and a standard deviation of 1 what is the probability of selecting a number between 7 and 13?

0.9974

Step-by-step explanation:

Let X be the random variable that follows the normal distribution \.

If mean () = 10 and standard deviation () =1

then, the probability of selecting a number between 7 and 13 =

                    [Since ]

Hence, the probability of selecting a number between 7 and 13 is 0.9974.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
