What is the formula for calculating net present value npv. The binomial distribution is frequently used to model the number of successes in a sample of size n drawn with replacement from a population of size n. From the definition of expected value and the probability mass function for the binomial distribution of n trials of probability of success p, we can demonstrate that our intuition matches with the fruits of mathematical rigor. Methods and formulas for probability density function pdf. This is the probability of having x successes in a series of n independent trials when the probability of success in any one of the trials is p. Understand the concept of internal rate of return irr and its relationship to npv.
And just so you understand, the probability of finding a single point in that area cannot be one because the idea is that the total area under the curve is one unless maybe its a delta function. The np chart is useful when its easy to count the number of defective items and the sample size is always the same. Normal distributions are often used in the natural and social sciences to represent realvalued random variables whose distributions are not known. Sometimes you need to do certain utility tasks such as formatting a date range, evaluating a functionformula, or doing array calculations. Exploring normal distribution with jupyter notebook. The ratio is computed by dividing the gross profit figure by net sales.

Net realizable value nrv is the amount by which the estimated selling price of an asset exceeds the sum of any additional costs expected to be incurred on the sale of the asset. If the sampling is carried out without replacement, the draws are not independent and so the resulting distribution is a hypergeometric distribution, not a binomial one.
