Answer:

Roll 2 dice until you get a sum of 8 and record how many trials you made.

Explanation:

A binomial experiment consists in an experiment that is done "n" number of times, and there are only 2 possible outcomes, one of whic would be called successfull, and failure. In this case there are only two outcomes, either you get 8 when rolling the dice, or not, the successfull outcome will be when you get 8 from the sum of the dice, and the failure will be when you get anythin else. The outcomes of this experiments must be independient from one another, this means that for example, the successful result in one try, shouldn´t compromise the possibilities of having another succesfull outcome in the next try.
