Enter the number of failures and the time period into the calculator to determine the failure probability. This calculator helps to evaluate the likelihood of failure within a given time frame.
Failure Probability Formula
The following formula is used to calculate the failure probability.
P_f = (n / t) * 100
Variables:
- P_f is the failure probability (%)
- n is the number of failures
- t is the time period
To calculate the failure probability, divide the number of failures by the time period and then multiply by 100 to convert it to a percentage.
What is Failure Probability?
Failure probability is a measure of the likelihood that a system or component will fail within a specified time period. It is often used in reliability engineering to assess the performance and safety of products and systems. The probability is usually expressed as a percentage, indicating the chance of failure per unit of time.
How to Calculate Failure Probability?
The following steps outline how to calculate the Failure Probability.
- First, determine the number of failures (n) that have occurred.
- Next, determine the time period (t) over which the failures were observed.
- Next, gather the formula from above = P_f = (n / t) * 100.
- Finally, calculate the Failure Probability (P_f) in percentage.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
number of failures (n) = 5
time period (t) = 12 months
