"Risk probability" does not quite make sense, perhaps you mean just how to calculate risk. There are many formulas and methods, a lot of them highly complex mathematical models. Risk calculation The formula for standard deviation is sqrt([sample size][probability of success](1-[probability of success])). To find the sample size from the mean and success rate, you divide the mean by the success rate. If mean=10 and success=0.2, you do 10/0.2 to get your sample size, or 50 in this case. Then you do sqrt(50*0.2*(1-0.2) to get about 2.83

This means that the probability your random sample will have 20 – 40% inner city students is 85.71%. TI 83 Central Limit Theorem: Overview . Watch the video or read the article below: The TI 83 calculator has a built in function that can help you calculate probabilities of central theorem word problems, which usually contain the phrase “assume the distribution is normal” (or a variation If you enter a probability as a percentage, be sure to include the percent sign (%) after the number. The check boxes and corresponding text entry areas let you constrain the range of values for which to find the probability. If a box is not checked, there is no constraint in that direction. For example if the box in front of >= is not checked
