To determine the probability that a randomly chosen person from this group is male, follow these steps:
1. Identify the total number of males in the group:
According to the table, the total number of male students is 229.
2. Identify the total number of people in the group:
The table provides that the grand total of students (both male and female combined) is 479.
3. Calculate the probability:
The probability of selecting a male randomly from the group can be found by dividing the number of males by the total number of people.
Probability [tex]\( P(\text{Male}) \)[/tex] =
[tex]\[
\frac{\text{Number of Males}}{\text{Total Number of People}} = \frac{229}{479}
\][/tex]
4. Round the result to two decimal places:
The calculated probability of [tex]\(\frac{229}{479}\)[/tex] is approximately 0.48 when rounded to two decimal places.
Therefore, the probability that a randomly chosen person from this group is male is [tex]\(\boxed{0.48}\)[/tex].
Thus, the correct answer is:
B. 0.48
