Heart Rates For a certain group of individuals, the average heart rate is 70 beats per minute. Assume the variable is normally distributed and the standard deviation is 3 beats per minute. If a subject is selected at random, find the probability that the person has the following heart rate. Use a graphing calculator. Round the answers to four decimal places. Part 1 of 3 Between 66 and 72 beats per minute. P(6668) = 0.7475 Part: 2/3 Part 3 of 3 Less than 74 beats per minute. P(X<74) = %3D

Just need help with part 3, thank you!
![Heart Rates For a certain group of individuals, the average heart rate is 70 beats per minute. Assume the variable is normally distributed and the standard
deviation is 3 beats per minute. If a subject is selected at random, find the probability that the person has the following heart rate. Use a graphing calculator.
Round the answers to four decimal places.
Part 1 of 3
Between 66 and 72 beats per minute.
P(66<X<72) = 0.6567
Correct Answer:
P(66<X<72) =0.6563
Part 2 of 3
Higher than 68 beats per minute.
P(X>68) = 0.7475
Part: 2/3
Part 3 of 3
Less than 74 beats per minute.
P(X<74) =D
