You arrive at a bus stop at 10 O'clock, knowing that the bus will arrive at some time uniformly distributed between $10$ and $10:30$. what is the probability that you wait longer than $10$ minutes? if at $10:15$ the bus has not arrived what is the probability that you will have to wait at least an additional $10$ minutes?
Im confused as to if im supposed to take $P( 5<x<10)$ assuming bus arrives at $10:15$, or $P(15<x<20)$ assuming bus arrives at $10:30$. Is this even right? please help!
