WebConstructing Probability Models. Suppose we roll a six-sided number cube. Rolling a number cube is an example of an experiment, or an activity with an observable result. The numbers on the cube are possible results, or outcomes, of this experiment. The set of all possible outcomes of an experiment is called the sample space of the experiment. WebFeb 8, 2024 · To find the percentage of a determined probability, simply convert the resulting number by 100. For example, in the example for calculating the probability of rolling a “6” on two dice: P (A and B) = 1/6 x 1/6 = 1/36. Take 1/36 to get the decimal and multiple by 100 to get the percentage: 1/36 = 0.0278 x 100 = 2.78%. how many stonehenge stones
