What is the probability of rolling a die and having it land on a factor of 30?
Daniel [21]

Answer:

So, since there is an equal chance to roll any number on a six sided die, that means the chance of rolling any one number is one out of 6 or 1/6. You can see that with a diagram. Now, rolling two different numbers in a specific order you can tell with a diagram is 1/36.

VLD [36.1K]

Answer:

E = 3.46\ movies

Step-by-step explanation:

The formula to find the error is:

E = z_{\frac{\alpha}{2}}\frac{\sigma}{\sqrt{n}}

Where:

\sigma is the standard deviation

n is the sample size

So

n = 80 people

\sigma = 12 movies

Then

1- \alpha = confidence level = 0.99

\alpha= 1-0.99

\alpha = 0.01\\\\\frac{\alpha}{2} = 0.005

We look for the Z value: Z_{0.005}

Z_{0.005}=2.58  Looking in the normal standard tables

Therefore:

E =2.58*\frac{12}{\sqrt{80}}\\\\E = 3.46\ movies
