Anew surgical procedure is successful with probability of p. assume that the operation is performed 5 times and the results are independent of one another. find the following probabilities. (you may use excel if you want) what is the probability that all five operations are successful if p = 0.8? what is the probability that exactly four are successful is p = 0.6? what is the probability that less than two are successful is p = 0.3? what is the expected value of the number of successful operations when p = 0.5? what is the variance of the number of successful operations when p = 0.4?

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
