In 1898, L. J. Bortkiewicz published a book entitled The Law of Small Numbers. He used data collected over 20 years to show that

Answer: Hence, Probability of more than 1 death in a corps in a year is 0.126.

Step-by-step explanation:

Since we have given that

Mean for a poisson distribution (λ) = 0.61

Number of years = 20 years

We need to find the probability of more than 1 death in a corps in a year.

P(X>1)=1-P(X=0)-P(X=1)

Here,

$P(X=0)=\dfrac{e^{-0.61}(0.61)^0}{0!}=0.543\\\\and\\\\P(X=1)=\dfrac{e^{-0.61}(0.61)}{1}=0.331$

So,

P(X>1)=1-0.543-0.331=0.126

Hence, Probability of more than 1 death in a corps in a year is 0.126.

Sarah and 2 friends go out to eat to a restaurant. Their bill is $89.50. In addition to the bill, they are going to leave a 20%

lbvjy [14]

Answer:

$111.87

Step-by-step explanation:

so you are going to divide this bill between two people. first you are going to divide 89.50 and divide it by 100. the answer you get you will multiply that by 20. that will be the tip they give so add that to 89.50. for the taxes you do the same but instead of multiplying by 20 you will multiply by 5. you are going to have to add that all up and then divide by 3.
