Question

Age 11

Answer 1

Using the probability concept, it is found that there is a $\frac{2}{5}$ 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:

$p = \frac{4}{10} = \frac{2}{5}$

There is a $\frac{2}{5}$ probability the student is a boy.
