Rule of combination

The rule of combination is a principle in probability that helps us find the likelihood of combined events happening together. It involves multiplying the probability of one event by the probability of another event, assuming the events are independent (not affecting each other). For example, if there's a 60% chance it will rain today and a 50% chance you'll receive a package, the probability of both happening is 0.6 × 0.5 = 0.3 or 30%. This rule simplifies calculating complex chances by breaking them down into manageable parts.
