Question 1(d)

2. Relevant equations

3. The attempt at a solution

So I know this is a conditional probability question.

Now I would have said

P(X>8) / P(X=5)

because it is probability I will NOT be served (i.e: time is greater than 8 mins) given I have already waited 5 mins

this gives me infinity because x/0 = inifinty

How do I approach this question?
