I made tape of a conversation. The recording began 34 minutes into a 60 minute tape and lasted 12 minutes. I inadvertently erased 18 minutes of the tape. What is the probability that I erased the whole conversation?
What are your thoughts?

The whole conversation will be erased - if you start erasing between 28 minutes and 34 minutes (then a 18 minute erasure will completely erase 12 minuteconversation.
Now calculate the probability that you will start erasing the 60 minute tape within those 6 minutes.
Now if the full 18 min were actually erased from the tape does that mean that the total possibility of a start time is reduced from the 60 minute tape length? Or does it mean we could have started erasing the tape at 50 min and 'erased the tape' for 18 minutes?
