Girl age is 11 years old
Fathers age is 39 years old
How to solve it:
Let the girls age be x years
Let the fathers age be (x+28) years
X+X+28=50
2x=50-28
2x=22
X=11
(11+28)= 39
Using permutations and the probability concept, it is found that there is a 0.0417 = 4.17% probability that Nia is chosen as president.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- As there are different roles, the order in which the students are chosen is important, hence, the <em>permutation </em>formula is used to solve this question.
Permutation formula:
The number of possible permutations of x elements from a set of n elements is given by:
Desired outcomes:
- For the other roles, 3 students from a set of 23, hence:

Total outcomes:
4 students from a set of 24, hence:

Then:

0.0417 = 4.17% probability that Nia is chosen as president.

w-4=-12-3w
Add 12 to each side:
w + 8 = -3w
Subtract 1w from each side:
8 = -4w
Divide both sides by -4:
w = 8 / -4
w = -2
