Question

Five tickets remain for this weekend’s Iron Slug and the Slime concert. Internet purchases arriving at the box office web site after opening time follow a Poison process with a sales rate of 30 transactions per minute. It takes 10 seconds to fill an order and I see that there are only two tickets remaining when I place the order at 10 seconds past the opening time. What are my chances of securing a single ticket (only one ticket per transaction is permitted)? Read carefully, as this is a trick question and there is a lot of missing information. Show all work and explanations.
