In deciding upon the appropriate premium to charge, insurance companies sometimes use the exponential principle, defined as follows. With X as the random amount that it will have to pay in claims, the premium charged by the insurance company is P = 1/a ln(E(e aX )) where a is some specified positive constant. Find P when X is exponential random variable with parameter lambda, and a = alpha lambda, where 0 < alpha < 1.

Step-by-step explanation:

The application of probability distribution function is employed in solving the question. The detailed analysis and step by step approach is as shown in the attached file.

i think that you should ask google for the answer to that problem because if we don't know it google does

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
