How to solve problems involving combinations
WebFlipping a coin two times, you get the combination { {hh}, {th}, {tt}} (the set of subsets). Yet, the chance of you getting heads-tails and tails-heads is not 1/3, its 2/4. Then, the probabilities of this set becomes {1/4 {tt}, 1/2 {th}, 1/4 {tt}} and it is not an equiprobable set. WebJul 18, 2024 · Many times we need to calculate the probability that an event will happen at least once in many trials. The calculation can get quite complicated if there are more than a couple of trials. Using the complement to calculate the probability can simplify the problem considerably. The following example will help you understand the formula.
