Cumulative Distribution Function Here is the function F(t) = { 0, t<1, 1/4, 1=<t<3, 1/2, 3=<t<5, 3/4, 5=<t<7, 1, t=>7, I have to find a. P(T=5) b. P(T>3) c. P(1.4<T<6) So for a. would that be 1/4? b. 1/2 c. I'm not sure. Thanks

I suggest you reflect on that fact, together with the definition of a cdf. The answer to (c) is Pr(T = 3) + Pr(T = 5) = ....
