The average number of students visiting a professor during her office hour is 2. Use an appropriate probability distribution used in this class to find the probability that 3 or more students will visit during her next office hour.
Answer to four decimal places.
Homework Answers
Average = 2 per hour
Hence by using Poisson distribution:
P(3 or more)
= 1 - P(Less than 3)
= 1 - [P(0) + P(1) + P(2)]
= 0.3233
