To solve this problem, we need to find the probability that a randomly chosen person from this group is male. Here's a step-by-step approach:
1. Determine the total number of people:
The total number of people is given as 479. This is the sum of all males and females.
2. Determine the total number of males:
From the table, we see that the total number of males is 229.
3. Calculate the probability:
The probability that a randomly chosen person is male can be calculated using the formula:
[tex]\[
\text{Probability of male} = \frac{\text{Number of males}}{\text{Total number of people}}
\][/tex]
4. Substitute the numbers into the formula:
[tex]\[
\text{Probability of male} = \frac{229}{479}
\][/tex]
5. Simplify and convert to decimal form:
Performing the division, we get approximately 0.4780793319415449.
6. Round the answer to two decimal places:
Rounding 0.4780793319415449 to two decimal places gives us 0.48.
Therefore, the probability that a randomly chosen person from this group is male, rounded to two decimal places, is 0.48.
So, the correct answer is B. 0.48.
