Determine whether each experiment is a binomial experiment. If it is, specify the values of n, p, and q, and list the possible values of the random variable x.

If it is not, explain why.

1. A certain surgical procedure has an 85% chance of success. A doctor performs the procedure on eight patients. The random variable represents the number of successful surgeries.

2. A jar contains five red marbles, nine blue marbles, and six green marbles.

You randomly select three marbles from the jar, without replacement. The random variable represents the number of red marbles.
