Determine a single event with a single outcome The first step to solving a probability problem is to determine the 2. Identify the total number of outcomes that can occur Next, you need to determine the number of outcomes that can 3. Divide the number of events. Identify the number of possible outcomes For any event, all the possible outcomes must be identified first. These should Identify the number of favorable outcomes Once all the possible outcomes of an event are identified, the number of Calculate the probability Once all the numbers are. Probability of drawing a blue and then black marble using the probabilities calculated above: P(A ∩ B) = P(A) × P(B|A) = (3/10) × (7/9) = Union of A and B. In probability, the union of events, P(A U B), essentially. It can be calculated by multiplying P (A and B) i.e. Joint Probability of event A and event B divided by P (B), Probability of event B Conditional Probability P (A|B) = P (A and B) / P (B) Conditional probability is used only when there are two or more than two events are happening. How to Calculate Probability Method 1 of 3: Finding the Probability of a Single Random Event. Choose an event with mutually exclusive outcomes. Method 2 of 3: Calculating the Probability of Multiple Random Events. Deal with each probability separately to calculate Method 3 of 3: Converting Odds. Multiply all probabilities together. So the result is:. Both independent and conditional probability are covered. Example 2 : A jar contains 4 blue marbles, 5 red marbles and 11 white marbles.

Probabilities can be written as fractions, decimals or percentages. Figure 2. Sample data to calculate probability. We want to calculate the probability that a product sales is between 50 and Calculating probability. To perform the calculation, we enter this formula in cell C11 = PROB (B4:B7, C4:C7, C9, C10) Where B4:B7 is the range containing the values for product sales, C4:C7 contains the probabilities. The probability of something which is impossible to happen is 0. The probability of something not happening is 1 minus the probability that it will happen. This video is a guide to probability.
