Clarification Needed Q1-3
When we say that the probability of something bad happening (E_{in} deviating from E_{out}) is at most delta, what do we mean?

a) n \leq \frac{1}{2\epsilon^{2}} ln\frac{2M}{\delta}
b) n \geq \frac{1}{2\epsilon^{2}} ln\frac{2M}{\delta}

The derivation from Hoeffding leads to case a) whereby for M = 1 I get [edited out by admin] or something like that as the value of n. Does this mean I have to select the value less than this one i.e. [edited out by admin] or the one above it that is greater than [edited out by admin] ...

Re: Clarification Needed Q1-3
If N is sufficient, then any number bigger than N is also sufficient.

The question asks what is the least number of examples needed, so among other things, that number would be itself sufficient.

BTW, when you post answers, please have *ANSWER* in the title per the instructions in the top announcement. Thank you.
