Probability Question

Yar, dont mind but I have seen in many of your posts, you give more emphasis on solving the question rather than learning from it I might be wrong but I cant resist myself pointing out something. :-D

This problem is little ambiguous and might not appear on the exam. If you read my previous post again I have clearly mentioned that
"Read the question in red, it said time in between 6-9 that means we should exclude the case 9:00.
The person will start at 6:00 and end at 8:59. He does not look at the 9:00 value."

He will start at 6:00:00 , at 6:00:01 ( here 01 are secs) he will still see 6:00 on the digital clock. This will be continued till 8:59:59. As he will look at the clock between 6:00 and 9:00, he still has 60 secs post 6:00 to consider 6:00 case.
This is the reason 6:00 is included and 9:00 is not.

PS: Don't mind for my harsh words, that's my way to motivate people.
If you are not able to understand anything, you are always welcome. But I advice you to spend some time,even an hour to know your doubt. Learning from own mistakes is the best way to learn.
