To determine the probability that a randomly chosen person from this group is male, we will follow these steps:
1. Identify the total number of male students:
From the table, the total number of male students is 229.
2. Identify the total number of students:
The total number of students, which includes both male and female students, is 479.
3. Calculate the probability:
The probability of selecting a male student is the number of male students divided by the total number of students. Mathematically, this can be expressed as:
[tex]\[
P(\text{Male}) = \frac{\text{Number of Male Students}}{\text{Total Number of Students}}
\][/tex]
4. Substitute the known values:
Substitute the numbers into the probability formula:
[tex]\[
P(\text{Male}) = \frac{229}{479}
\][/tex]
5. Simplify and round the result to two decimal places:
Calculating this fraction yields approximately 0.4781. Rounded to two decimal places, the probability is 0.48.
So, the probability that a randomly chosen person from this group is male is:
[tex]\[
\boxed{0.48}
\][/tex]
Thus, the correct answer is:
[tex]\[
\boxed{B}
\][/tex]
