# Marginal and conditional density

Not what you're looking for?

A tobacco company produces blends of tobacco with each blend containing various proportions of Turkish, domestic and other tobacco.

The proportion of Turkish and domestic in a blend are random variables (X = Turkish and Y = domestic) with joint density function

f (x,y) = { 24xy, 0 < or= x < or=1, 0 < or = y < or=1

x + y < or=1

0, elsewhere

A. Find the marginal density for the proportion of the domestic tobacco.

B. Find the conditional density of X given Y = 3/4

C. Find the probability that the proportion of Turkish tobacco is less than 1/8, given that the blend contains 3/4 domestic tobacco.
