The area under a smooth curve gives the probability of values falling within a certain range and is found by taking the definite integral of a probability density function. This curve is called the ...

A discrete random variable is a type of random variable that can take on a countable set of distinct values. Common examples include the number of children in a family, the outcome of rolling a die, ...

In Excel, syntax for this function is NORMINV(probability,mean,standard deviation). Using the sales example, with a weekly sales average of $2,000 that fluctuates about $500 up or down, you know ...

The bell curve, or normal distribution, ... to calculate the confidence interval of normal probability distribution, a representation of the distribution of random variables whose real ...

So the Bernoulli random variable X can have a value of 1 for the probability of success, say p, and a value of 0 for the likelihood of failure, say q or 1-p. The outcomes of other trials have no ...

Elements of the probability distribution. There are the following functions used to obtain the probability distributions: Probability mass function: This function gives the similarity probability ...

Probability distributions are used to highlight a market participant's read on an asset return's sensitivity, when the return is seen as a random variable. Probability distributions are ...
