Simple probability examples
The best example for understanding probability is flipping a coin: There are two possible outcomes—heads or tails. What’s the probability of the coin landing on Heads? We can find out using the equation P (H) = ? P (H) =? . You might intuitively know that the likelihood is half/half, or 50%. But how do we work that out? Probability = In this case: WebbProbability with counting outcomes Example: All the ways you can flip a coin Die rolling probability Subsets of sample spaces Practice Subsets of sample spaces Get 3 of 4 …
