WebStep 1: Change the given percentage to a decimal. In our example: 76% = 0.76. Step 2:. Multiply the decimal found in step 1 by itself. Repeat for as many times as you are asked to choose an item. For example, if you were to pick 3 items at random, multiply 0.76 by itself 3 times: 0.76 x 0.76 x 0.76 = .4389 (rounded to 4 decimal places). WebJun 9, 2024 · The number of times a value occurs in a sample is determined by its probability of occurrence. Probability is a number between 0 and 1 that says how likely something is to occur: 0 means it’s impossible. 1 means it’s certain. The higher the probability of a value, the higher its frequency in a sample.
