Probability quantifies the likelihood of an event occurring, specifically in scenarios where each outcome is equally probable []. The fundamental calculation involves dividing the number of favorable outcomes by the total number of possible outcomes []. For instance, when rolling a die, the probability of rolling a specific number like five is one (favorable outcome) out of six (total outcomes), resulting in 1/6 []. Conversely, the probability of an impossible event, like rolling a seven on a standard die, is zero [], while a sure event, such as rolling either an even or odd number, has a probability of one []. Probabilities always fall within the range of 0 to 1, or 0% to 100% when expressed as percentages [].
