I need your help with these:

Answer the following question:

1. We define probabilities for various normal distributions. However, we use one single table (Standard Normal Distribution Table) for all of them. Explain why that is possible.

Are these true or False

2. Drawing 5 marbles from a bag with 10 red, 8 green and 12 yellow marbles without replacement and finding out how many of these five are green is a binomial experiment.

3. Randomly generated numbers follow a uniform distribution, not a normal distribution.

4. Because the tails of the normal distribution curve are infinitely long, the total area under the curve is also infinite.
