What event has the same chance of happening?

Events that have the same chance of happening are typically those that are mutually exclusive and have equal probabilities. For example, flipping a fair coin has an equal chance of landing on heads or tails, each with a probability of 50%. Similarly, rolling a fair six-sided die results in each number (1 through 6) having a 1 in 6 chance of being rolled. These events are independent and demonstrate equal likelihood in their outcomes.
