Homework Statement
Suppose that two events occur in an hour, and the probability is uniformly distributed. If the time that the first event occurs has the same distribution as the time that the second event occurs, and the two distributions are independent, what is the probability that the second event occurs at least 20 minutes after the first?
Homework Equations
The distribution is uniform (i.e. pmf=1/60 for each minute).
The Attempt at a Solution
I'm not sure how to approach this problem. I couldn't find a pattern with this table:
Time of E1, probability of E1 during that time, probability E2 is 20 mins before E1
0..20, 20/60, 0/60
21, 1/60, 1/60
22, 1/60, 2/60
23, 1/60, 3/60,
