Bob was away last week and did not engage with the contents of the lectures of his modules. This week he is back again but hasn't catched up with the lectures yet. Let X be the proportion of material that he will understand in this week's Probability lecture, and Y the proportion of material he will understand in this week's Calculus lecture. The joint probability density function for the two random variables is of the form fxy(x,y) = 1.4 x + 0.6 y, for 0

to find the value of A and B for:
fx(x) = Ax + B

Bob was away last week and did not engage with the contents of the lectures of his modules. This week he is back again but hasn't catched up with the lectures yet. Let X be the proportion of material that he will understand in this week's Probability lecture, and Y the proportion of material he will understand in this week's Calculus lecture. The joint probability density function for the two random variables is of the form fxy(x,y) = 1.4 x + 0.6 y, for 0<x<1, 0<y<1 0, otherwise Give your answers to the following questions to two decimal places. (a) The marginal probability density function of the proportion of material he will understand in the Probability lecture is given by: fx(x) = Ax+ B, for 0<x<1 0, elsewhere Find the value of A. Answer: Find the value of B. Answer:
