Question

Adam teaches a class on probability calculus. Students have noticed that Adam is generally 3 minutes late, and the irregularity with which he appears in class deviates from the average by 7 minutes. Assuming that the instructor's appearance time in a probability calculus class has a normal distribution, determine the probability that the class will not be held (the instructor will be more than 15 min late).

Duration of the class is 90 minutes.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
