Click here to view page 1 of the cumulative standardized normal distribution table.
Click here to view page 2 of the cumulative standardized normal distribution table.
a. What is the probability that X> 75?
The probability that X > 75 is
(Round to four decimal places as needed.)
b. What is the probability that X< 90?
The probability that X < 90 is
(Round to four decimal places as needed.)
c. What is the probability that X< 85 or X > 125?
