The Poisson distribution is a discrete distribution that calculates the likelihood that a certain number of events will occur within a certain amount of time.
The probability of getting exactly three robberies in a day is 0.1607.
<h3>What is meant by poison distribution?</h3>
The Poisson distribution is a discrete probability distribution used in probability theory and statistics to express the likelihood that a given number of events will occur within a specified time or space interval if they occur at a known constant mean rate and regardless of the interval since the last event.
The Poisson distribution is a discrete distribution that calculates the likelihood that a certain number of events will occur within a certain amount of time.
In the poison distribution a discrete random variable X has the following probability mass function,
, where
is the mean of the distribution and
Given that 
The required probability, 
Therefore, the probability of getting exactly three robberies in a day is = 0.1607.

Answer:
D. y-5 = 3(x+1)
Step-by-step explanation:
Slope of the perpendicular line is 3.
Slope intercept form is,
y-5 = 3 (x-(-1))
y-5 = 3(x+1)
Answer:
The correct way to interpret the difference of a number divided by 6 and 5 equals 8 is
n/6 - 5 = 8. I believe that another tutor has misled you; there should be only one division, applying to n only.
Answer: 25x^2 - 1^2
Explanation:
(5x+1) (5x-1)
(5x)^2 - 1^2
25x^2 - 1^2
