According to the Ministry of Public Education, schools in Samarkand have closed an average of 24 days each year due to some type of emergencies. Assume that the number of school closure days can be approximated by a Poisson distribution. What is the probability that a randomly chosen school in Samarkand will close for 1 or 2 days next month?

Using the Poisson distribution, it is found that there is a 0.5414 = 54.14% probability that a randomly chosen school in Samarkand will close for 1 or 2 days next month.

We have the mean in an interval, hence, the Poisson distribution is used.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

The parameters are:

Average of 24 days each year, considering that a year has 12 months, the monthly mean is of

Then:

In which

0.5414 = 54.14% probability that a randomly chosen school in Samarkand will close for 1 or 2 days next month.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
