WebTo find the probability of an event happening we use the formula \text {Probability}=\frac {\text {number of desired outcomes}} {\text {total number of outcomes}} Probability = total number of outcomesnumber of desired outcomes For example, Let’s look at the probability of getting an even number when a die is rolled. WebIn other words, since the mean is 0.15 and we want to figure out what the probability that it's greater than 0.10, then the distance from our proportion to the mean is 0.05. Divide this number by the standard deviation to see how many std. dev. it is away from the mean, so 0.05/0.028, and we get 1.77.
