To determine the probability that a randomly chosen person from the given group is female, we need to follow these steps:
1. Identify the total number of people in the group: According to the table, the total number of people is 479.
2. Identify the total number of females in the group: The table indicates that there are 250 females.
3. Calculate the probability of selecting a female: The probability of an event happening can be calculated using the formula:
[tex]\[
P(\text{Female}) = \frac{\text{Number of females}}{\text{Total number of people}}
\][/tex]
Plugging in the numbers from the table:
[tex]\[
P(\text{Female}) = \frac{250}{479}
\][/tex]
4. Simplify the fraction and convert it to a decimal: When you divide 250 by 479, you get approximately 0.5219206680584552.
5. Round the decimal to two decimal places: The precise value of 0.5219206680584552 rounds to 0.52 when rounded to two decimal places.
Thus, the probability that a randomly chosen person from this group is female is approximately 0.52.
Therefore, the correct answer is:
B. 0.52
