# What is probability and impact?

Probability and Impact Matrix is a tool for the project team to aid in prioritizing risks. For example, a risk with a high probability/ likelihood of occurring and which will have a high impact on the project objectives will likely need a response plan.

Thereof, what is risk probability and impact?

In risk analysis, risk is traditionally defined as a function of probability and impact. The probability is the likelihood of an event occurring and the consequences, to which extent the project is affected by an event, are the impacts of risk.

One may also ask, how do you calculate risk impact? For businesses, technology risk is governed by one equation: Risk = Likelihood x Impact. This means that the total amount of risk exposure is the probability of an unfortunate event occurring, multiplied by the potential impact or damage incurred by the event.

One may also ask, what is the difference between risk and impact?

You will be told that the Risk is an event that may or may not happen. You will also be told that Impact is what will happen if the Risk occurs (or 'eventuates').
