In an attempt to minimize no-shows on high-demand days a golf course has implemented an online check-in procedure. Preliminary results indicate that once a golfer has checked in, there is only at 20% chance that he or she will be a no-show. This chance of being a no-show can be modeled using the binomial distribution.
If 15 golfers have checked in using this process, what is the probability there will be exactly 4 no-shows among them?
If 15 golfers have checked in using this process, what is the probability there will be at least 4 no-shows among them?
If 15 golfers have checked in using this process, what is the expected number and standard deviation of no-shows among these golfers?
