What is the probability of rolling a sum of 8 on a standard pair of six-sided dice? express your answer as a fraction or a decim
maxonik [38]
First lets see how many combinations there are that make 8 from the numbers 1-6:

2+6
3+5
4+4
5+3
and 6+2. 

Note: the order does matter, because you roll two die. This means the first die has a number and the second die also has a number. 2 on 1st dice and 6 on 2nd dice would be a different combination than 2 on 2nd dice and 6 on 1st dice.

Now we calculate the probability of getting a number 2 through 6 on the first dice: which is 5/6.

Then calculate the probability of getting a number that pairs up with the first number to make 8: *Note: once you get a number 2 through 6, there is only one other number that you can roll to make 8. This means the probability of getting a match would be 1/6 on the 2nd dice.

Finally, multiply the two fractions we got earlier: 5/6 x 1/6 = 5/36

Your probability would be 5/36 in fraction form, 13.89% in percent form, or 0.139 in decimal form rounded 3 places.

Hope this helps, and May the Force Be With You!

Please help solve by elimination I hope its not blurry Have a nice day and Goodnight
strojnjashka [21]

Answer:

\displaystyle \textcolor{black}{4.}\:[-3, -5]

\displaystyle \textcolor{black}{3.}\:[8, -1]

\displaystyle \textcolor{black}{2.}\:[4, -7]

\displaystyle \textcolor{black}{1.}\:[3, -2]

Step-by-step explanation:

When using the Elimination method, you eradicate one pair of variables so they are set to zero. It does not matter which pair is selected:

\displaystyle \left \{ {{2x - 3y = 9} \atop {-5x - 3y = 30}} \right.

{2x - 3y = 9

{⅖[−5x - 3y = 30]

\displaystyle \left \{ {{2x - 3y = 9} \atop {-2x - 1\frac{1}{5}y = 12}} \right. \\ \\ \frac{-4\frac{1}{5}y}{-4\frac{1}{5}} = \frac{21}{-4\frac{1}{5}} \\ \\ \boxed{y = -5, x = -3}

------------------------------------------------------------------------------------------

\displaystyle \left \{ {{x - 2y = 10} \atop {x + 3y = 5}} \right.

{x - 2y = 10

{⅔[x + 3y = 5]

\displaystyle \left \{ {{x - 2y = 10} \atop {\frac{2}{3}x + 2y = 3\frac{1}{3}}} \right. \\ \\ \frac{1\frac{2}{3}x}{1\frac{2}{3}} = \frac{13\frac{1}{3}}{1\frac{2}{3}} \\ \\ \boxed{x = 8, y = -1}

_______________________________________________

\displaystyle \left \{ {{y = -3x + 5} \atop {y = -8x + 25}} \right.

{y = −3x + 5

{−⅜[y = −8x + 25]

\displaystyle \left \{ {{y = -3x + 5} \atop {-\frac{3}{8}y = 3x - 9\frac{3}{8}}} \right. \\ \\ \frac{\frac{5}{8}y}{\frac{5}{8}} = \frac{-4\frac{3}{8}}{\frac{5}{8}} \\ \\ \boxed{y = -7, x = 4}

------------------------------------------------------------------------------------------

\displaystyle \left \{ {{y = -x + 1} \atop {y = 4x - 14}} \right.

{y = −x + 1

{¼[y = 4x - 14]

\displaystyle \left \{ {{y = -x + 1} \atop {\frac{1}{4}y = x - 3\frac{1}{2}}} \right. \\ \\ \frac{1\frac{1}{4}y}{1\frac{1}{4}} = \frac{-2\frac{1}{2}}{1\frac{1}{4}} \\ \\ \boxed{y = -2, x = 3}
