Question

a) Find:
i) the value of a ,

ii) the probability that the price is lower than the total sales.

b) Determine the conditional probability density function of Y given X .

Suppose X, the price of a certain surgical face mask (in RM) and Y, the total sales (in 10,000
units) are random variables whose joint distribution function given by:
a+ ху ,0 <x<1, 0<у<1
f(x,у)-
,elsewhere
