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.

y = 7
I have attached the step explanation in the photo
The answer should be 18.6, just substitute x for 2 and y for 3 and solve using PEMDAS :)
Answer:
x = 52, y = 26
Step-by-step explanation:
x - 2y = 0
40 - y = 14
(40 - 40) - y = 14 - 40
- y = -26
y = 26
x - 2(26) = 0
x - 52 = 0
x (- 52 + 52) = 0 + 52
x = 52
Answer:
3.162278
Step-by-step explanation:
√10= 3.16227766
then find the millionths place which is 3.16227766
then you round that number based on the number to the right of it which is a 6 so you round it up
so the answer is 3.162278
