Poisson: A newborn is considered to have low birth weight if it is less than 2500 grams. A materity ward has experienced 210 cases of low birth weight for one vear. Find the probability that on a given day, there are 3 babies born with low birth weight.
Added by Alfonso B.
Step 1
To do this, we need to divide the total number of low birth weight cases in one year by the number of days in a year. Total low birth weight cases = 210 Number of days in a year = 365 Average rate per day = 210 / 365 ≈ 0.575 cases per day Show more…

Use the Poisson distribution to find the indicated probabilities. Low Birth Weight $A$ newborn baby is considered to have a low birth weight if is weighs less than 2500 grams. Such babies often require extra care. Dutchos County, New York, has been experiencing a mean of 210.0 cases of low birth weight catch year. a. Find the mean number of low birth weight babies born catch day. b. Find the probability that on a given day, there is more than 1 baby born with a low birth weight. c. Is it unusual to have more than 1 low birth weight baby born in a day? Why or why not?
Discrete Probability Distributions
Poisson Probability Distributions
On average, 2.5 babies are born each day at a local hospital. Assuming the Poisson distribution, what is the probability that no babies are born today?
Adi S.
Assume that the Poisson Distribution applies to the number of births at a particular hospital during a randomly selected day. Assume that the mean number of births per day at this hospital is 11.7189. Find the probability of that in a day there will be at least one birth.
