Jojodrdru,

Welcome to AMHD.com

The query you put up here, belongs to probability, and seems to be direct out of some exercise book. It is not much difficult. But you first try and write here, where does the problem arise, or at which level of the sum, do you face problem(s)?

I mean - how to begin?
How to get to middle?
How to end?

Or, is the answer you find does not compare with the answer in the text/exercise book?

I wait for your reaction, and attempt!
