If X has a uniform distribution on an interval S, that X must take avalue in the interval S. Hence, the p.d.f f(x) of X must be 0 outside of S. Furthermore, since a, y particular subinterval of S having a given length is likely to contain X as is any other subinterval having the same length, regardless of the location of the particular subinterval in S, it follows that f(x) must be constant throughout S. Also
∫_(-∞)^∞▒〖f(x)dx=∫_a^b▒〖f(x)dx=1〗〗 (3.2.4)
