In a recent study concerning family plan, it is found out that the age at firstmarriage for women is normally distributed with a mean equal to 25.3 yearsand a standard deviation is 2.5 years. The random variable for this event is:X = number of marriages for women.X = mean age at first marriage for women.O x = age at first marriage for women.X = age of marriage for women.The following four questions are based on the problem below.According to a recent report, the average number of accidental drowning people in one yearis 36 people. If a medical practitioner wants to know the probability that 20 or more people aredrowning in one year, answer the following questions:
