Percentage Probability Calculator: Are you wondering How can be possible for finding the probability using a percent? Don't get worried anymore as we have come up with the best solution ie., the percent probability calculator. With this free online probability percentage calculator tool, you can easily find the percentage probabilities within no time and understand how to compute these percent probability questions manually.

How to Find the Percentage Probability?

The steps that everyone should follow while calculating the percentage probabilities of an event are fashioned:

  • First and foremost, compute the number of favorable outcomes in a common situation.
  • Understand the number of chances of the desired event happening.
  • Now, determine the total number of possible events or else the total number of choices for the outcome of the event.
  • In this step, we have to divide the number of outcomes desired by the number of possible events.
  • At last, work on the result by moving the decimal point to the right two places or product the decimal by 100. Then, you will get the percent probability outcome for an event.

Let's understand this concept completely from the below percentage probability example and gain more knowledge on it.

Percentage Probability Questions / Examples


Neil has a standard deck of 52 cards. What is the probability that he will select a heart when she draws a card at random?


Given deck has 52 cards

In the deck, there are 12 hearts

Hence, 13 chances for Neil to draw out a heart

There are 52 cards in the deck so Neil has 52 possible outcomes

At this point, divide 13 by 52 i.e., 13/52 = 0.25

To calculate the percentage probability, we have to multiply the decimal by 100 ie., 0.25 x 100 = 25

Therefore, Neil has a 25 percent chance of selecting a heart at random.
