Let X be the number of scoring chances that result in goals for a football team during n scoring chances. During many games, the team scores on 20% of the chances. a) Explain why it might be reasonable (at least as an approximation) to assume that X is binomially distributed in this situation. Do this by going through each of the points that must be met for us to use the binomial distribution, assess whether it is reasonable for them to be met here and specify any additional assumptions we need to make.
Whether a customer at a carry-out restaurant leaves a tip is a random variable. The probability that a customer leaves a tip is 0.42. The probability that one customer leaves a tip is independent of whether another customer leaves a tip. Let leaving a tip represent a “success” and not leaving a tip represent a “failure.” Does this problem describe a discrete or continuous random variable? What kind probability distribution fits the random variable described in this problem? What is the probability that a customer does not leave a tip? Calculate the mean and variance of this distribution. What is the probability that on a day with 100 customers, exactly 50 of them leave a tip?
