What is the probability that the web site has between 3 million and 4 million visitors in a single day? If needed, round your an
faust18 [17]

Answer:

0.2196

Step-by-step explanation:

Given that

Mean = 4.56 million visitors per day

Standard deviation = 820,000 visitors per day

According to the given situation the calculation of probability is shown below:-

Here we will find the value of P (3 ≤ X ≤ 4)  

P 93\leq X\leq 4)=P(X\leq 4) - P(X\leq 3)

\\=P(\frac{X-\mu}{\sigma}\leq  \frac{4-4.56}{0.82})-P(\frac{X-\mu}{\sigma}\leq  \frac{3-4.56}{0.82})

\\=P(Z\leq -0.683)-P(Z\leq -1.9024

= 0.2483 - 0.0287

= 0.2196

Therefore the probability that the web site has between 3 million and 4 million visitors in a single day is 0.2196

If you have 144 cars then we divide 144 by 3 to get 48

That is not the answer though because that would be a 3/1 ratio

We then multiply 48 by 2 to get 96
