1 Let X and Y be two continuous random variables with joint probability
density function
f(x, y) = 0.25x^2 + y/c; -1<= x
<= 1, 0; otherwise.

a) Compute the value of c.
b) Produce the marginal probability density function of Y.
c) Calculate P(X > 0,Y <1).
d) Calculate P(X>0|Y <1).
e) Calculate P(X + Y > 0).

step-by-step explanation:

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
