5. The monthly sales of an electronic company are approximately normally distributed with a mean of RM2.5 million and a standard deviation RM300 000. a) Find the probability that the total sales for a particular month is at least RM3 million. b) If the monthly break-even sales amount is RM1.8 million, find the probability that the total sales for a particular month will exceed this amount. c) If the company randomly take a sample of 12-month sales record, will the distribution of the 12 months' samples be approximately normal based on the Central Limit Theorem (CLT)? Justify your answer.
