Q1. The public health center in the "BigRock" town knows that daily demand for Covid-19 vaccine kits is normally distributed with a mean of 100 and a standard deviation of 15. Answer with rounding to 3 decimal places. 1) What is the probability that the demand in a day will exceed 125? 2) What is the probability that the demand will be less than 75? 3) How many vaccine kits should be stocked daily in the center to ensure that all daily demands will be met with 95% probability? (Hint: Note that kits can be stocked only in integer numbers.)
