The probability of choosing Joey first is 1/12 .
If that happens, the probability of choosing Chloe next is 1/11 .
Then, the probability of choosing Zoe after that is 1/10 .
The probability of all these things happening is
(1/12) x (1/11) x (1/10)
= 1/1320 = 0.00076 = 0.076 percent
I'm assuming we have to solve for "p" here...
By making an equation, we will get...
(p/4)-4=10
Add four on both sides...
(p/4)=14
Remove parentheses and multiply by four on both sides.
p=56
Using the probability concept, it is found that there is a
probability the student is a boy.
<h3>What is a probability?</h3>
- A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
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:

There is a
probability the student is a boy.

X+ 9 = 32
x = 32-9
so,
option c is correct.
x + 9 = 32
9 = 32 - x
so, option d is also correct.
