NettetSolution 2. This is a solution with out usage of any package. You can compute the probability to draw at least one 1 by this formula (mentioned by @whuber): p = 1 − ∏ i = 1 n ( 1 − 1 d i) where n is the number of dices and d i is the number of sides of dice i. Then you can define a function in R with one argument dices, where dices is a ... NettetSo, the probability of rolling an even number on a die is 3∕6 = 1∕2. Since the five dice are independent events, we can multiply their probabilities together, so the probability that all five dice show even numbers is (1∕2)⁵ = 1∕32. …
