Question

General hospital has noted that they admit an average of 8 patients per hour. what is the probability that during the next two hours exactly 8 patients will be admitted

Answer 1

According to question

Average Number of patients in one hour = 8

Thus 
Average Number of Patients in 2 hours = 8 * 2 = 16

So
Probability of admitting 8 patients in 2 hours = 8 / 16 = 1/2

Thus The Probability is 1/2
