|\Omega|=6\\ |A|=4\\\\ P(A)=\dfrac{4}{6}=\dfrac{2}{3}\approx67\%

If we will roll a fair die then the outcomes wil be 1,2,3,4,5,6.

Hence, the total number of events= 6

3,4,5 and 6 are greater than 2.

So, there's 4 events which are greater than 2.

Now the formula to find the probability is:

probability=\frac{Number of events more than 2}{Total number of events.}

=\frac{4}{6}

=\frac{2}{3}

So, the probability of getting greater than a 2 is 2/3.

Help me please !! i need the answer

Answer:

PQ=22\\\\QR=7\\\\PR=29

Step-by-step explanation:

To find the value of y, you can create an equation where two parts of the line are equal to the whole line:

PQ+QR=PR

Substitute given values:

(8y+6)+(y+5)=(19y-9)

Solve for y. Simplify parentheses:

8y+6+y+5=19y-9

Combine like terms to simplify the equation:

8y+y+6+5=19y-9\\\\9y+11=19y-9

Get the variable on one side of the equation and the constants on the other. Add 9 to both sides:

9y+11+9=19y-9+9\\\\9y+20=19y

Subtract 9y from both sides:

9y-9y+20=19y-9y\\\\20=10y

Isolate the variable. Divide both sides by 10:

\frac{20}{10} =\frac{10y}{10} \\\\y=2

The value of y is 2. Insert this value into each line segment value and solve:

PQ=8(2)+6\\\\PQ=16+6\\\\PQ=22

QR=(2)+5\\\\QR=7

PR=19(2)-9\\\\PR=38-9\\\\PR=29

:Done

You can check by using:

PQ+QR=PR\\\\22+7=29

This statement is true, so the values are correct.
