I got these answers for,
1. D, for continuous f(x) = lim, but info on limit is given and not on the value of function at x=3, so D
12. D, Since, uniform distribution fu. then P.M.F. = 1/10
15. C, just add xf(x) for x=1,2,3,4,5
I am getting D for 8, A for 10, B for 18 and can't solve 19,21,22,23,24.
Please, explain.
