hey,
I have a question from your "praticeprob.pdf." can you explain how you got 1/9 for the first problem?

The problem asks for the odd in favor of selecting digit 7 out of a set of 10 numbers.
You have 1 favorable & 9 non favorable events.
Hence odds in favor of selecting 7 are: 1/9

These words are terrifying but it will became interesting and easy when you have a good knowledge about permutation and combination.
