    GIVEN: A dice is thrown once. TO FIND: Probability of getting a prime number. Total number on a dice is 6. Prime numbers on a dice are 2, 3 and 5. Total number of prime numbers on dice is 3 `"We know that PROBABILITY"="Number of favourable event"/"Total number of event"` `"Hence probability of getting a prime number" = 3/6=1/2` Therefore, the denominator is six. To find the numerator, count the number of favorable outcomes. Let's try some examples. Example 1. A die is rolled once. What is the probability of getting an odd number? Solution. The following outcomes are favorable: getting number 1, getting number 3, or getting number 5. If you want to get really technical, all risks except ones you completely avoid can fall into the accept category. If a particular risk is low impact and has a low probability of occurring, you won't need to monitor it as frequently. It is more of a getting ahead of risk - sort of estimating the future risk profile.On a fair 6-sided die, each number has an equal probability p of being rolled. when a fair die is rolled n times, the most likely outcome (the mean) is that each number will be rolled NP times, with a standard deviation of sqrt NP (1-P).
