**Discrete Mathematics**Level 4

A letter is known to have come either from **'TATA NAGAR'** or from **'CALCUTTA'**. On the envelope, just two consecutive letters **TA** are visible.
What is the probability that the letter came from **'TATA NAGAR'**?
The answer will be in the form of \(\frac{p}{q}\), where \(p\) and \(q\) are coprime positive integers, find \(p+q\).
