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:

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
