Answer:

See below.

Explanation:

19.

The spinner has 12 equal-sized sections.

1/3 of 12 = 4

A number that appears in exactly 4 sections has a probability of 1/3. The number 3 appears exactly 3 times.

A number that appears more than 4 times has a probability greater than 1/3. The number 0 appears exactly 5 times.

A number that appears fewer that 4 times has a probability of less than 1/3.

Both 1 and 2 appear fewer than 4 times.

Answer:

Probability greater than 1/3: 0

Probability equal to 1/3: 3

Probability less that 1/3: 1, 2

20.

The amount of concentrate is 12 gallons.

The total amount of drink is 40 gallons.

The fraction of the concentrate out of the total is 12/40.

12/40 = 0.3

0.3 of each gallon is concentrate.

Color the bottom up to 0.30
