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:
- Nia's president.
- 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.

Answer:
<h3> 1. a), </h3><h3> 2. c), </h3><h3> 3. b), </h3><h3> 4. a), </h3><h3> 5. a), </h3><h3> 6. c), </h3><h3> 7. ⁵/₃ or 5÷3 or 1 ²/₃</h3>Step-by-step explanation:
1. 0 divided by any number is always 0
2. 7×(5-5) = 7×0 = 0
3. Integers between -5 and 5 are:
-4, -3, -2, -1, 0, 1, 2, 3 and 4
4. - ( |5 - 11| ) = - ( |-6| ) = - ( 6 ) = -6
5. Numerical coefficient is the number with its sign. No letters.
6. x increased by y means: y more than x. And x+y = y+x
7. one third of 5 means so it is:
