How to use BINOMDIST function in Excel
Summary: This tutorial elaborates on how to use the BINOMDIST()
function in Excel, a function used to calculate the probability of a fixed number of successes in a fixed number of Bernoulli trials (experiments), each with the same probability of success.
Step 1: Understand the BINOMDIST function
The syntax for the BINOMDIST()
function is:
=BINOMDIST(number_s, trials, probability_s, cumulative)
Here's what each parameter represents:
number_s
: The number of successes in trials.trials
: The number of independent trials.probability_s
: The probability of success on each trial.cumulative
: A logical value that determines the form of the function. If TRUE, it returns the cumulative distribution function; if FALSE, it returns the probability mass function.
Step 2: Use the BINOMDIST function
Let's say you want to calculate the probability of getting exactly 5 heads in 10 coin flips (where the probability of getting a head on any given flip is 0.5). You can use the BINOMDIST()
function as follows:
=BINOMDIST(5, 10, 0.5, FALSE)
This function will return the probability of getting exactly 5 heads in 10 flips.
