Question
Select the appropriate response. bag contains 15 red balls and 3 green balls. One at a time a ball is selected, the color is recorded and the ball is returned to the bag. This is done until 100 balls have been pulled from the bag. X = number of outcomes that are red. Is X a binomial random variable? O Yes, is a binomial distribution.

O No, not a binomial because the probability of a success changes with each trial (the trials are not independent).
