-6 + 7 - 4 = -3

Sum = 24 Count = 4 Mean = Sum/Count = 24/4 = 6

7/4

Sum = 36 Count = 6 Average = Sum/Count = 36/6 = 6

On two 6-sided fair dice:Rolling a sum of 5: 4 out of 36, or 11.11%Rolling a sum of 7: 6 out of 36, or 16.67%Rolling a sum of either 5 or 7: 10 out of 36, or 27.78%Here's why: Look at the dice as unique, (maybe one is red and one is blue). Then there are 36 different possible outcomes.The four that give a sum of 5: 1+4, 2+3, 3+2, 4+1.The six that give sum of 7: 1+6, 2+5, 3+4, 4+3, 5+2, 6+1So there are 4 chances out of 36 (or 1 out of 9 = 11.11%) to get a sum of 5, and 6 chances out of 36 (or 1 out of 6 = 16.67%) to get a sum of 7. If you want either 5 or 7 as a sum, add the chances together to get 10 out of 36 (or 5 out of 18 = 27.78%)

4 and 3(4 + 3 = 7)or 1 and 6(1 + 6 = 7)or 5 and 2(5 + 2 = 7)

the sum of -2 and 6 and 7 is (-2+6+7)

Sum = 42 Count = 6 Mean = Sum/Count = 42/6 = 7

4+7+5+6+8=30 30 is the only sum those numbers can add up to.

There are 36 permutations of two dice. Of them, 6 have a sum of 7, (1+6, 2+5, 3+4, 4+3, 5+2, and 6+1) and 2 have a sum of 11 (5+6 and 6+5). The probability, then of getting a sum of 7 or 11 is (6 plus 2) in 36, or 8 in 36, or 2 in 9, or about 0.2222.

6 + 7 = 13(Sum means add)

Well since an equation has an equal sign it is 6+7=13

Half of 6 is 3. Half of 8 is 4. 7 is not an even number, so half of 7 will not be a round number. Half of 7 is halfway between half of 6 and 8-halfway between 3 and 4. So half of 7 is 3.5 Additionally, you could multiply 7 by .5 to divide it in half. Your answer will be 3.5, for the reason explained above.

You get the largest sum if you add all of the numbers.

Half of 12 is 6

2/4 = 6/12 7/6 = 14/12 6/12 + 14/12 = 20/12 or 5/3

6+7

It is -7,-6,-5,-4!

It is 6+7 = 13.

Sum of -13 and 7 is -6.
