If you need to apply probability theory in practice, you can use the following calculation algorithm:

Determine one event with one result. First, you need to determine the probability that you want to calculate. For example, you need to know the probability that a roll of the die will yield a deuce.

Find out the total number of scenarios that can occur. During step one, you determined the event. If you refer to the dice roll example, the total number of scenarios is six, because there are six numbers on the die. So a roll of two can have six different scenarios.

Divide the number of events by the number of possible scenarios. Falling two during the first die roll is one event. It turns out that the probability of falling two is 1/6, and the probability of not falling two is 5/6. This results in a 1/5 or 20% chance of getting a deuce on the first roll.

But how do you calculate the probability with multiple random events? Your steps are as follows:

Determine each of the events you will be working with. Say you need to find the probability of a four on each of two different dice.

Calculate the probability for each event separately. It will be 1/6. This will also allow you to determine the probability of a four falling on two dice at the same time.

Multiply all the probabilities. In our dice example, 1/6×1/6 = 1/36 is the odds that a four will fall on two dice at the same time.

If you find it difficult to figure out probability theory on your own, you can always ask a tutor. A professional tutor will show you how this theory works to solve real life and professional assignments. You will not only be able to discover this useful section of mathematics, but also to apply it to work and practical situations.
