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

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.
