Use continuous random variables - calculation checkpoint

A school canteen waiting time is uniformly distributed on \([0,6]\). Find \(P(1\le X\le 3)\). This version asks for the same mathematical quantity after confirming the method from the context. Enter the requested value and choose the interpretation that matches the result.

Worked practice: result and interpretation

Calculate the requested result first, then choose the interpretation that follows from it.
