Welcome to probability! Probability is a way to measure how likely something is to happen. Think of flipping a coin - there are two possible outcomes: heads or tails. Since both outcomes are equally likely, the probability of getting heads is one half, or 0.5. Probability is always a number between 0 and 1, where 0 means impossible and 1 means certain. Let's learn the key terms in probability. An experiment is any action where we don't know the outcome for sure, like rolling a die. An outcome is one possible result, such as rolling a 4. The sample space is the set of all possible outcomes - for a six-sided die, that's the numbers 1 through 6. An event is what we're specifically interested in, like rolling an even number or getting a 4. Now let's learn the basic probability formula. The probability of an event equals the number of favorable outcomes divided by the total number of possible outcomes. This always gives us a number between 0 and 1. For example, if we want to find the probability of rolling a 3 on a six-sided die, there's only 1 favorable outcome - rolling a 3. The total number of outcomes is 6. So the probability is 1 divided by 6, which equals approximately 0.167. Understanding the probability scale is crucial. Probability is always between 0 and 1. Zero means impossible - like rolling a 7 on a six-sided die. One means certain - like rolling less than 7 on that same die. And 0.5 means equally likely - like flipping heads on a fair coin. This scale helps us understand how likely or unlikely different events are.
