I have a question:
Let X be a random variable with a given PMF of:
x | 0 | 2 | 4 | 5
p(x) |0.15 | 0.30 | 0.30 | 0.25
I need to calculate
P[ 2 < X < 4]
would this simply be 0? The question does not specify whether it is a discrete random variable or a continuous random variable.
In the event it is a continuous random variable, how do I find the answer?
