Three dice are rolled. Let the random variable x represent the sum of the 3 dice. By assuming that each of the 63 possible outco

<h3>Answer:  1/8</h3>

In decimal form, 1/8 = 0.125 which converts to 12.5%

==================================================

Work Shown:

The 63 should be 6^3. There are 6 choices per slot, and 3 slots, so 6^3 = 216 different outcomes.

Here are all of the ways to add to 11 if we had 3 dice

  1. sum = 1+4+6 = 11
  2. sum = 1+5+5 = 11
  3. sum = 1+6+4 = 11
  4. sum = 2+3+6 = 11
  5. sum = 2+4+5 = 11
  6. sum = 2+5+4 = 11
  7. sum = 2+6+3 = 11
  8. sum = 3+2+6 = 11
  9. sum = 3+3+5 = 11
  10. sum = 3+4+4 = 11
  11. sum = 3+5+3 = 11
  12. sum = 3+6+2 = 11
  13. sum = 4+1+6 = 11
  14. sum = 4+2+5 = 11
  15. sum = 4+3+4 = 11
  16. sum = 4+4+3 = 11
  17. sum = 4+5+2 = 11
  18. sum = 4+6+1 = 11
  19. sum = 5+1+5 = 11
  20. sum = 5+2+4 = 11
  21. sum = 5+3+3 = 11
  22. sum = 5+4+2 = 11
  23. sum = 5+5+1 = 11
  24. sum = 6+1+4 = 11
  25. sum = 6+2+3 = 11
  26. sum = 6+3+2 = 11
  27. sum = 6+4+1 = 11

There are 27 ways to add to 11  using 3 dice. This is out of 216 total outcomes of 3 dice being rolled.

So, 27/216 = (1*27)/(8*27) = 1/8 is the probability of getting 3 dice to add to 11.

|x-3|+4=12 show all steps <br>Please
SOVA2 [1]

Answer:

|x-3|+4 = 12

|x-3| = 12-4

|x-3| = 8

now solve for both positive and negative values

x - 3 = 8      |   x - 3 = -8

x = 8 + 3     |   x = - 8 + 3

x = 11          |    x = -5

solution set : { 11, -5 }

10 Pts + Brainliest for the best answer.
Harrizon [31]

Answer:

NVU =150

Step-by-step explanation:

WVN + NVU = WVU

We know NVU = 2x+150  and WVU = x+176  and WVN = 26

Substituting these in

26+ 2x+150 = x+176

Combine like terms

176+2x= x+176

Subtract 176 from each side

176-176+2x= x+176-176

2x=x

Subtract x from each side

2x-x = x-x

x=0

NVU = 2x+150

        0+150

NVU =150

Simplify by combining like terms.<br> 12−a+a+12<br> Thanks!
OLEGan [10]
The like terms are the a terms and the constants. If you combine them, you will get 24, as the negative a and the positive a cancel each other out.
