Consider the random variable X that represents the number of peoplewho are hospualized or died in a single head-on collision on the road in front ofa particular spot in a year. The distribution of such random variables is typicallyobtained from historical data. Without getting into the statistical aspects involved,let us suppose that the CDF of X is as follows:x 01 2 3F(x) 0.250 0.546 0.898 0.932 0.955 0.972 0.981 0.989 0.995 0.998 1.00046 7 89.10Find P(X 10) and P(X < 5/X > 2).

Let x be a random variable that represents hemoglobin count (HC) in grams per 100 milliliters of whole blood. Then x has a distribution that is approximately normal, with population mean of about 14 for healthy adult women.

Storm damage can occur to homes in any given year, with the amount of damage varying randomly from year to year. Let X represent the dollar value of storm damage in a given year. It is known that in 95% of the years, X = $0, while in 5% of the years, X = $20,000. What is the expected value and standard deviation of the damage in any given year?
