The table contains a hospital's probability distribution chart of the number of babies born per day for a week. Determine the missing probability in the distribution, and then answer this question: What percentage of time should a sufficient number of nurses be on duty to care for at least seven babies?
The probability of more than seven babies being born on any given day is (0.4375 + 0.1875+0)= 0.625. So a sufficient number of nurses to be on duty to care for at least seven babies is needed 62.5% of the time.
