Basic Notation Help Taking a robotic planning class and have no stats background. I am just trying to understand what this means:
"What is the probability of the event $R=\{x||x-1|\le 1\}$?"
Can someone tell me in plain words what the $R$ statement is saying? In the problem we are only given that mean$=1$, and variance$=1$. I read the whole chapter this question is based on and could not find a similar instance of this notation.
Thanks

$X$ is a random variable, the question is asking for what is the probability that event $R$ occur where $R$ is the event that $|X-1| \le 1$.
The condition is equivalent to   $0 \le X \le 2$.
I don't think there is sufficient information unless you make more assumptions.
