A parabolic satellite dish reflects signals to the dish's focal point. An antenna designer analyzed signals transmitted to a satellite dish and obtained the probability density function f(x)= c(1- 1/16x^2) for 0
a. Value of c that makes f(x) a valid probability density function.
b. P(X<=0.4)=
c. P(0.1 < x <0.4)=
