It is possible to calculate the probabilities for a binomial random variable X by using the following formula for p (x): where n is the number of trials that will be performed.The required number of successes is denoted by the letter x.The number of failures is represented by n – x.

- The chance of success on any particular trial is denoted by the letter p.
- The likelihood of failure on each particular trial is represented by the number 1 – p.

## How to calculate probability with z score not on table?

- Zoe has a z-score of 1.25, whereas Mike has a z-score of 1.0.
- When working with negative z-scores, it’s vital to remember that you may simply utilize a table that has negative z-scores to solve your problem.
