Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What condition must be met to use the normal distribution to approximate the binomial distribution?
A large sample (n > 25) and p, the probability of success on each trial = around 0.5 (0.35 to 0.65).
Independence is already assumed for it to be binomial.
