Suppose a drawer contains six white socks, three brown socks, and seven black socks. We draw one sock from the drawer and it is

mojhsa [17]

Answer:

The probability is $1$ .

Step-by-step explanation:

We have a drawer that contains :

Six white socks
Three brown socks
Seven black socks

Let's define the following events :

W : '' The sock we got was white ''

Br : '' The sock we got was brown ''

Bl : '' The sock we got was black ''

We can calculate the following probabilities by counting :

$P(W)=\frac{6}{16}$

Because there are 6 white socks out of 16 socks in the drawer

Using the same reasoning :

$P(Br)=\frac{3}{16}$

$P(Bl)=\frac{7}{16}$

Now to calculate the probability of getting at least two socks of the same color we need to think about the following :

Getting at least two socks of the same color means getting two, three or four (except the brown socks because we only have three brown socks) of the same color.

Again we can calculate the probability by counting :

$\frac{FavorableCases}{TotalCases}$

But giving that we pull out four socks, we always will get at least two socks of the same color.

In the most desfavorable case we will get one white sock, one brown sock and one black sock. And in the last extraction we will complete it with a white, brown or black sock (obtaining two socks of the same color).

Finally, all extractions of four socks will have at least two of the same color.

The probability is $1$ .

A gym membership costs $110 to open and $30 per month after

Softa [21]

Answer:

1) The dependent variable is the monthly charge and the independent variable is the $110 to open the membership.

2)The dependent variable is the monthly charge because it will change depending on how many months you plan to keep your membership.

3)This relationship is linear because it will go up by $30 every month.

4)You could create a graph off of this information because all you would need to do is graph the cost each month.

5)I would need the number of month that I would keep the membership going and the amount that i have already paid.
