In probability, the independent event is when the outcome of one event does not affect the outcome of another. For example, if I pick a movie first, that doesn't change the chances of picking bowling or skating next. If I have 4 activities (movie, bowling, skating, arcade) and I pick a movie first and don’t replace it, I have 3 remaining activities to choose from, so for the month, I could have 3 different possible events after picking the movie first.
Your parents allow you to have an outing with your friends every Saturday of the month. You select the movies, bowling, skating, and the arcade as your activities for this month and put them on slips of paper in a jar to randomly select. In 3 sentences, in a 6th grader’s response describe the independent and dependent probabilities, then determine how many possible events you could have for the month if the movie outing is selected first and not replaced.
