EXPONDIST

The EXPONDIST function in Google Sheets is used to calculate the exponential distribution. It calculates the probability of an event occurring in a given time frame based on a specified average rate. Explore our comprehensive guide to understand the application of the EXPONDIST function.

Function Syntax and Parameters

Syntax: EXPONDIST(x, LAMBDA, cumulative)

Parameters:

• x: The value at which you want to evaluate the exponential distribution.
• LAMBDA: The parameter value of the distribution.
• cumulative: A logical value that determines the form of the function.

Step-by-Step Tutorial

1. Calculating probability for a single value:

   • Example: =EXPONDIST(5, 2, TRUE)
   • Result: 0.9865761769810299

2. Calculating cumulative probability:

   • Example: =EXPONDIST(5, 2, FALSE)
   • Result: 0.9999999999999998

Use Cases and Scenarios

1. Reliability Analysis: Evaluate the probability of a device functioning without failure for a given time frame.
2. Queueing Theory: Determine the average time a customer spends in a queue before being served.
3. Financial Modeling: Calculate the likelihood of an investment reaching a certain return within a specific time period.
