What is n in a binomial?
Properties of a binomial experiment (or Bernoulli trial) Fixed number of trials, n, which means that the experiment is repeated a specific number of times. The n trials are independent, which means that what happens on one trial does not influence the outcomes of other trials.

How does n affect binomial distribution?
The variance of the distribution increases with N as you are measuring the total number of successes, not the ratio. Imagine you throw a coin once. The variance is tiny as all possible results are 0 heads and 1 heads (1/2 of a success from the mean).

What is the binomial distribution with example?
In a binomial distribution, the probability of getting a success must remain the same for the trials we are investigating. For example, when tossing a coin, the probability of flipping a coin is ½ or 0.5 for every trial we conduct, since there are only two possible outcomes.
