A ski resort claims that there is a 75% chance of snow on any given day in january and that snowfall happens independently from
creativ13 [48]

The mean exists at 3 and the standard deviation exists 0.87.

Using the binomial distribution, it exists seen that the mean and the standard deviation of X exist given as follows:

$\mu_{X}=3, \sigma_{X}=0.87

<h3>What is the binomial probability distribution?</h3>

The expected value of the binomial distribution exists:

$\mu_{X}=n p$$

The standard deviation of the binomial distribution exists:

$\sigma_{X}=\sqrt{n p(1-p)}$$

In this problem, the proportion and the sample size exist given as follows:

p = 0.75

n = 4

Therefore, the mean and the standard deviation exist given by:

$&\mu_{X}=n p=4(0.75)=3 \\

$&\sigma_{X}=\sqrt{n p(1-p)}

$=\sqrt{4(0.75)(0.25)}=0.87

The mean exists at 3 and the standard deviation exists 0.87.

To learn about the binomial distribution refer to:

Expression.is of what number? Write a division expression to match this question.
nirvana33 [79]

3/4 is 1/3 of what number?

For this problem we just need to do the following division:

\frac{x}{3}=\frac{3}{4}

And we can solve for the value of x desired and we got multiplying both sides by 3:

x=3(\frac{3}{4})=\frac{9}{4}

So then we can conclude that 3/4 is 1/3 of 9/4

Answer: 9/4

Expression:

\frac{x}{3}=\frac{3}{4}
