3- What portion of your company's staff is female and on the sales forces?
B About 55% of emergency room visits are unnecessary, assuming each emergency room visit is independent. (Hint: first define the random variable x then write the objective of each question in terms of x.
1 if you randomly select 15 patients from those visiting the emergency department what is the chance that all of them need tobe in the emergence.
2 What is expected number from the 15 randomly selected patients, who do not need to be in the emergency room and what is the standard deviation of the number?
3 Suppose the distribution of unnecessary emergency room visits can be approximated by normal distribution what is the probability that at least two of them need be in the emergency room?
