During the dry month of August, one U.S. city has measurable rain on average only 4 days per month. Assume all months have 30 da
Doss [256]

Answer:

The average number of days that will pass between measurable rain is 7.5.

Step-by-step explanation:

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

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given time interval.

The expected period between the event happening is \frac{1}{\mu}

During the dry month of August, one U.S. city has measurable rain on average only 4 days per month. Assume all months have 30 days.

This means that

\mu = \frac{4}{30}

(a) If the arrival of rainy days is Poisson distributed in this city during the month of August, what is the average number of days that will pass between measurable rain? *

\frac{1}{\frac{4}{30}} = \frac{30}{4} = 7.5

The average number of days that will pass between measurable rain is 7.5.
