How many links in a foot?
There are 100 links in a chain. There are 66 feet in one chain. Therefore, one foot is equal to 100/66 = 1.51 recurring (that is, 1.515151...) links.
How many links do you need to join 30 pieces of chain in to one long chain?
15
What is the purpose of probability distribution?
A probability distribution links the probability of an outcome in a statistical experiment with the chances of it happening. Probability distributions are often used in statistical analysis.
What are the functions of middlemen in the chain of distribution?

Define a normal random variable?
I have included two links. A normal random variable is a random variable whose associated probability distribution is the normal probability distribution. By definition, a random variable has to have an associated distribution. The normal distribution (probability density function) is defined by a mathematical formula with a mean and standard deviation as parameters. The normal distribution is ofter called a bell-shaped curve, because of its symmetrical shape. It is not the only symmetrical distribution. The two links should provide more information beyond this simple definition.
