In this video, we explore the probabilities associated with winning a lottery. We start with a simple lottery where 3 numbers are chosen from 12. We'll calculate the probability of winning with a single ticket, and how that changes if you have multiple tickets. We'll also consider scenarios with multiple winning sets and the probability of winning at least once when holding multiple tickets. Courses on Khan Academy are always 100% free.
