How to understand this probability density function with continuous random variable Could anyone help me? I don't want the solution. Instead I'm just looking to understand what this means:
x 
2

Is this the Binomial Coefficient? How is this related with PDF?


I would guess it's supposed to be $\frac x2$ and there's been a printing issue. Notice that if that's the case $f(x)$ is non-negative and integrates to 1 and so is a probability distribution.
