Hi I was given this question in an exam and unfortunately didnt know how to do it obtaining zero out of seven.
A continuous random variable, X, had density function of the form
where a and b are constants(i) calculate the values of a and b.
I figured since the integral of the density function from to is 1, a and b could be derived but i don't get anywhere.
here is my working:-
which gives me Im not exactly sure but i think this gives me roughly ab=1,,,do i just sub then for instance back into my original integral??? im not sure as this gives me
If anyone could give me some idea as to how I could get a reasonable or solid answer you'll be very helpful!!!
