Thirty-five percent of teens buy soda (pop) at least once each week. Eleven kids are randomly selected. The random variable represents the number of these kids who purchase soda (pop) at least once each week. For this to be a binomial experiment, what assumption needs to be made?

All eleven kids selected live in the same region

All the kids eligible to be selected are teens

All teens have the same probability of being selected

The probability of being a teen and being a kid should be the same
