BINOMDIST

The BINOMDIST function in Google Sheets calculates the probability of drawing a certain number of successes (or a maximum number of successes) in a certain number of tries given a population of a certain size containing a certain number of successes, with replacement of draws.

Function Syntax and Parameters

Syntax: BINOMDIST(num_successes, num_trials, prob_success, cumulative)

Parameters:

• num_successes: The number of successes desired.
• num_trials: The number of independent trials.
• prob_success: The probability of success in each trial.
• cumulative: [Optional] A logical value that determines the type of probability distribution to use.

Step-by-Step Tutorial

1. Calculating the probability of a certain number of successes:

   • Example: =BINOMDIST(3,10,0.5,FALSE)
   • Result: 0.1171875

2. Calculating the cumulative probability:

   • Example: =BINOMDIST(3,10,0.5,TRUE)
   • Result: 0.171875

Use Cases and Scenarios

1. Probability of Success: Calculate the probability of a certain number of successes in a given number of trials.
2. Statistical Analysis: Determine the likelihood of achieving a specific outcome in a series of independent events.
3. Quality Control: Analyze the probability of a certain number of defective items in a production batch.
