Assume the random variable X follows a Binomial Distribution with number of trial n and probability of success p. The probability mass function of the distribution is give as follows: P(X = x) = Qp*q"-, x = 0,1,2,..,n. Il y = 1-p Then show that E(X) = np and V(X) = npq. ​

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
