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.
