During the Movement Control Order (MCO) in Malaysia, the price of a face mask had been controlled and is approximated by a normal distribution model with an average price of RM 1.50 and standard deviation of RM 0.50. If a face mask is chosen at random, determine the probability that the face mask price is: i. less than RM 1 ii. more than RM 2 iii. between RM 1.20 to RM 1.80 iv. at least RM 2.50 V. at most RM 1.90 b.

At a tennis tournament a statistician keeps track of every serve. The statistician finds that the mean serve speed of a particular player was 110 miles per hour (mph) and the standard deviation of the serve speeds was 5 mph.
