#PROBABILITY OF PERCENTAGES CALCULATOR HOW TO#

P(red and number and face) = P(red) x P(number|red) x P(face|red and number) For example, if we want to calculate the probability of getting a red card, a number card, and a face card in a standard deck of cards, we can use the multiplication rule of probability to calculate: This formula can be used to calculate the probability of complex events that depend on multiple factors. In words, this formula states that the probability of n events occurring is equal to the probability of the first event multiplied by the probability of the second event given that the first event has occurred, multiplied by the probability of the third event given that both the first and second events have occurred, and so on, up to the probability of the nth event given that all previous events have occurred. P(A1 and A2 and … and An) = P(A1) x P(A2|A1) x P(A3|A1 and A2) x … x P(An|A1 and A2 and … and An-1) The general formula for the probability of n events occurring is: This formula is known as the multiplication rule of probability and can be extended to any number of events. Where P(A) is the probability of event A occurring, P(B|A) is the probability of event B occurring given that event A has occurred, and P(C|A and B) is the probability of event C occurring given that both event A and event B have occurred. P(A and B and C) = P(A) x P(B|A) x P(C|A and B)

The probability of three events occurring can be calculated using the formula: If you choose, you may modify the unit to a decimal values. Keep in mind that each probability must be a value between 0 and 1 (or in percentage values as 0% and 100%, respectively). You may also enter two numbers in the first and second portions of this calculator. probability of none of the events happening:.the probability of one of three occurrences occurring precisely once:.the chances of all three occurrences occurring are as follows:.at least one of the following three events is likely to occur:.The calculator will output the following once you’ve completed the three fields: First, change the units to decimal value and enter the probability (possible chance) of each event as a percentage. This probability calculator may be used for three separate, random events.

These worksheets explain how to calculate probability as a decimal, a fraction, and a percentage. When finished with this set of worksheets, students will be able to recognize basic properties of a parabola by studying its equation. It also includes ample worksheets for students to practice independently. This set of worksheets contains lessons, step-by-step solutions to sample problems, both simple and more complex problems, a review, and a quiz. Some problems may require that students convert the answer from one form to another. They will express probability in the form of a fraction. They will express probability in the form of a percentage. They will express probability in the form of a decimal. In these worksheets, students will practice calculating probability. To sum up, the probability of rolling a 3 with a number cube is 1 out of 6 and can be expressed in the forms explained above. Then, move the decimal point two places to the right to show the percent. To express this decimal as a percentage, multiply the decimal by 100. Now to express this fraction as a decimal, you may divide the numerator by the denominator.ġ/6 = 0.1666. You can write the same probability as a fraction simply by rewriting the two numbers in the ratio as the numerator and denominator of a fraction. Since any ratio can be converted into a fraction, percentage, or decimal, this means that any probability can be easily converted into a decimal, fraction, or percentage.įor example, when you roll a number cube, the probability of getting a '3' is: P(3) = favorable outcomes : total outcomes. You can compute a probability in terms of ratios. The probability of something happening can be expressed in multiple forms, as either a decimal, a percentage, or a fraction.
