A random variable is normally distributed with the mean of 50 and standard deviation of 5.  

a. Draw the normal curve for probability density function. Label the horizontal axis with values of 35, 40, 45, 50, 55, 60, and 65. The normal curve almost touches the horizontal axis at three standard deviations below and at three standard deviations above mean (in this case at 35 and 65).

b. Find out the probability the random variable will suppose a value between 45 and 55?

c. What is the probability the random variable will suppose a value between 40 and 60?
