Finding the Probability of "At Least One" Events - Study.com

Sometimes it’s easier to find what you don’t want and subtract from 1. [ P(\textevent) = 1 - P(\textcomplement) ] Example: "Probability of rolling at least one 6 in two rolls" is messy. But "not rolling a 6" twice is (5/6)×(5/6) = 25/36. Then 1 - 25/36 = 11/36. Finding the Probability of "At Least One" Events - Study

If you’re working on probability of simple events, you’re learning how likely it is for one specific outcome to happen. Finding the Probability of "At Least One" Events - Study

Probability always falls between 0 (impossible) and 1 (certain). If your answer is greater than 1, check your total outcome count. Finding the Probability of "At Least One" Events - Study
