The best answer is: A) uniform.

Explanation:

The sample space for the product of two dice is:

{1, 2, 3, 4, 5, 6

2, 4, 6, 8, 10, 12

3, 6, 9, 12, 15, 18

4, 8, 12, 16, 20, 24

5, 10, 15, 20, 25, 30

6, 12, 18, 24, 30, 36}

Using this, the theoretical probabilities are:

P(1) = 1/36

P(2) = 2/36

P(3) = 2/36

P(4) = 3/36

P(5) = 2/36

P(6) = 3/36

P(8) = 2/36

P(9) = 1/36

P(10) = 2/36

P(12) = 4/36

P(15) = 2/36

P(16) = 1/36

P(18) = 2/36

P(20) = 2/36

P(24) = 2/36

P(25) = 1/36

P(30) = 2/36

P(36) = 1/36

If a bar graph is drawn to represent this, we see that this is close to uniform. It is not exactly uniform, but it is definitely not symmetric; not positively skewed; and not negatively skewed.

lys-0071 [83]

Answer:

73.5

Step-by-step explanation:

To find the mean, sum the data and divide by the amount of data

mean = \frac{77+82+87+85+32+78}{6}

          = \frac{441}{6} = 73.5
