What is a binomial distribution?

Answer 1

See the full explanation presented.

When we have 100 coins and we give those coins to a set of people in any manner, it is said that we are distributing coins.

In a similar way, when the total probability (which is 1) is distributed among the different values associated with the random variable, we are distributing probability. Hence, it is called a probability distribution. If there is a rule that determines what probability should be assigned to which value, then such a rule is called the probability distribution function. The binomial distribution gets its name because the rule that determines the different probabilities are the terms of the binomial expansion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
