Answer:

I think the total number of combinations of 3 from 6 = 6C3 = 20

All possible combinations of 3 which have a product divisible by 3 must contain either a 3 or a 6.

So the number not divisible must be 3 combinations from the number 1, 2, 4, and 5.= which is 4

So the required probability is 20-4 ? 20 = 16/20 = 0.8 Answer

Hope this help you! :)

Answer:

\frac{y-2}{4}

Step-by-step explanation:

Let's start by factoring everything:

\dfrac{\frac{y^2+y}{y^2-2y}}{\frac{4y+4}{y^2-4y+4}}=

\dfrac{\frac{y(y+1)}{y(y-2)}}{\frac{4(y+1)}{(y-2)^2}}=

Now, you can cancel out some terms:

\dfrac{\frac{y+1}{y-2}}{\frac{4(y+1)}{(y-2)^2}}=

Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:

\frac{y+1}{y-2}\cdot \frac{(y-2)^2)}{4(y+1)}=

\frac{y-2}{4}

Hope this helps!

-1/9+-5/9=<br> Simplest form<br> 24 points
Nataly [62]

-1/9+-5/9=

When you are adding a negative number, the operation turns into subtraction:

-1/9-5/9=\frac{-1-5}{9}=-\frac{6}{9}=-\frac{2}{3}

Really, it's just subtraction. The simplest form is -2/3, which is equal to -0.66667.

I hope this helps :)
