Sagot :
Using the probability concept, it is found that there is a [tex]\frac{2}{5}[/tex] probability the student is a boy.
What is a probability?
- A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, according to the two-way table found on the internet when we research the problem:
- There are 11 people who are 12, of which 4 are girls and 7 are boys.
- Hence, in total, there are 21 people, of which 13 are girls and 8 are boys.
- Then, we find that there are 10 people aged 11, of which 6 are girls and 4 are boys.
Then:
[tex]p = \frac{4}{10} = \frac{2}{5}[/tex]
There is a [tex]\frac{2}{5}[/tex] probability the student is a boy.
