Web1. Binomial and Poisson distributions can only compute the probability of discrete variables, e.g. number of people, number of tests 2. Normal distributions compute the probability of continuous variables, e.g. time, money, kilometers. This is because the curve of a normal distribution never touches the x-axis. 3.

The Binomial distribution function is used when there are only two possible outcomes, a success or a faliure. A success occurs with the probability p and a failure with the probability 1-p. Suppose now that in n independent trials the binomial random variable X represents the number of successes. The following ...

WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs. For example, we can define rolling a 6 on a dice as a … Webthe Normal tables give the corresponding z-score as -1.645. (Negative because it is below the mean.)
