- Question: Identify the parameters pand n in the following binomial distribution scenario. The probability of winning an arcade game is 718 and the probability of losing is 0.282. If you play the arcade game 20 times, we want to know the probability of winning more than 15 times. (Consider winning as a success in the binomial distribution.)
