Question 1041051: A bag contains 7 red marbles and 8 green marbles. Anne picks 3 marbles at random, with replacement, and observes the color of each marble. The number of green marbles, X, is a binomial random variable. If we let success correspond to getting a green marble, what is the success probability, p? What is the number of trials?

The success probability is the number of ways that you can get a successful outcome in one trial divided by the total number of outcomes for one trial (the sum of the possible successful results plus the possible unsuccessful results). The number of trials is the number of draws.
