Let X1 , X2 , X3 , ... , be a list of random variables. We are going to add up the first n of them: X1 + X2 + + Xn

If we want to use a Normal curve to estimate the probability of what we will get, what must we know about these random variables? Select each requirement (one or more).

Each of them is continuous.

Each of them follows a Normal distribution.

Each of them is independent of all the others.

The number of terms n is sufficiently large.

Each of them is discrete.

Each of them has the same probability distibution.
