The histogram shows the reviewer ratings on a scale from 1 (lowest) to 5 (highest) of a recently published book.

(a) Find the mean, variance, and standard deviation of the probability distribution.

(b) Interpret the results.

Rating Probability 0.020 0.097 0.213 0.236 0.434

i believe the answer is the polygon, heptagon.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

step-by-step explanation:

the answer is 89 d
