Based on the data in the two-way table, what is the probability that a person consumes 1,500 to 2,000 calories in a day?

A. 0.22
B. 0.28
C. 0.35
D. 0.50

To find the probability that a person consumes between 1,500 and 2,000 calories in a day, follow these steps:

1. Identify the Total Number of People in the Survey:
- According to the table, the total number of people surveyed is 500.

2. Identify the Number of People Consuming 1,500 to 2,000 Calories:
- Look at the column labeled "1500 to 2000 cal.". The total number of people who consume calories in this range is 250.

3. Calculate the Probability:
- The probability is the number of people consuming calories in the desired range divided by the total number of people surveyed.
- So, the probability is calculated as:
[tex]\[
\text{Probability} = \frac{\text{Number of people consuming 1,500 to 2,000 calories}}{\text{Total number of people}}
\][/tex]
- Substituting the numbers, we get:
[tex]\[
\text{Probability} = \frac{250}{500} = 0.50
\][/tex]

The probability that a person consumes 1,500 to 2,000 calories in a day is 0.50.

Therefore, the correct answer is D. 0.50.
