1) (1 pt) You are investigating a random phenomenon and have determined that the cumulative distribution function F_{X}(x):=P(X<x) of the random variable X has values F_{X}(1)=.5, F_{X}(2)=.74, F_{X}(3)=.92
A) Less than 1 _____ B) Larger than 2 _____ C) Between 1 and 3 _____ 2) Equations: None that I know of that pertain to this particular problem. 3) Part A: 0.5+0.74+0.92=2.16 So... 0.5/2.16=0.23148 Or 23.148% I tried this for each part. I'm looking through my notes but they only have probability questions with equations.

So what does [itex]F_X(1)[/itex] signify? The answer to part a) is immediate. Can you now figure out the other two parts?
