1. Sample space:

{2, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9, 9, 10, 10, 10, 11, 11, 12}

2. Probabilities of getting each sum

Probability of getting 2: 1/36Probability of getting 3: 1/18Probability of getting 4: 1/12Probability of getting 5: 1/9Probability of getting 6: 5/36Probability of getting 7: 1/6Probability of getting 8: 5/36Probability of getting 9: 1/9Probability of getting 10: 1/12Probability of getting 11: 1/18Probability of getting 12: 1/36

Explanation:

1. Sample space.

Sample space is the set consituted by the total possible outcomes. Since each number cube has 6 possible outcomes, the number of possible outcomes when you toss two number cubes is 6×6 = 36. Thus, your sample space must have 36 elements.

You can found the sample space using a chart:

123456

1234567

2345678

3456789

45678910

567891011

6789101112

Hence, the sample space is the set of all the numbers inside the square:

{2, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9, 9, 10, 10, 10, 11, 11, 12}

2. Probabilities of getting each sum.

The probability of getting each sum is the number of times each sum appear in the sample space divided by the size of the sample space (36):

Probability of getting 2:

1/36

Probability of getting 3:

2/36 = 1/18

Probability of getting 4:

3/36 = 1/12

Probability of getting 5:

4/36 = 1/9

Probability of getting 6:

5/36

Probability of getting 7:

6/36 = 1/6

Probability of getting 8:

5/36

Probability of getting 9:

4/36 = 1/9

Probability of getting 10:

3/36 = 1/12

Probability of getting 11:

2/36 = 1/18

Probability of getting 12:

1/36

Answer from: Quest

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

Answer from: Quest

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
