An insurance salesman sells on average 10.4 life insurance policies per week. Find the probability that in a particular week he
Fittoniya [83]

Answer:

P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}, X= 0,1,2,...

P(X=8) = \frac{e^{-10.4} 10.4^8}{8!}= 0.1033

And that would be the solution for this case.

Step-by-step explanation:

Previous concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}, X= 0,1,2,...

Solution to the problem

Let X the random variable that represent the number of life insurance policies that the salesman person sells. We know that X \sim Poisson(\lambda=10.4)

And we want to find this probability:

P(X =8)

And we can use the probability mass function and we got:

P(X=8) = \frac{e^{-10.4} 10.4^8}{8!}= 0.1033

And that would be the solution for this case.

svetoff [14.1K]

Answer: I’m pretty sure it’s 1/9

Step-by-step explanation:

You multiply 1/3x1/3 because the probability she’s chooses soup is 1/3. And the probability of her choosing juice is 1/3. The reason those are 1/3 because she has 3 things to choose from and she’s choosing one of them. So now you multiply 1/3 x 1/3 witch will get you 1/9. Hope this helps! HAVE A GOOD DAY!
