Suppose that f (x) = 1.5x2 for -1 < x < 1 and f (x) = 0 otherwise. Determine the following probabilities.
(a)P(0 < X)
(b)P(0.5 < X)
(c)P(-0.5 ≤ X ≤ 0.5)
(d)P(X<-2)
(e)P(X < 0 or X>-0.5)
(f) Determine x such that P(x < X) = 0.05.
Can you tell me how you got them? I have a TI 89 and it has built in functions too if that makes it easier to explain.
Also, just doing a) would probably enable me to finish the rest.
Thanks! It's urgent!!!
