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:

P_{(n,x)} = \frac{n!}{(n-x)!}

Desired outcomes:

  • Nia's president.
  • For the other roles, 3 students from a set of 23, hence:

D = P_{23,3} = \frac{23!}{20!} = 10626

Total outcomes:

4 students from a set of 24, hence:

T = P_{24,4} = \frac{24!}{20!} = 255024

Then:

p = \frac{D}{T} = \frac{10626}{255024} = 0.0417

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

A standard working day is 8 hours, if you were to work 125% of a normal day, how many total hours would you work?
Elodia [21]

Answer:

10 hours

Step-by-step explanation:

It is given that,

Standard working day is 8 hours

If you were to work 125% of a normal day, then it means that,

125\%\ \text{of}\ 8\ \text{hours}\\\\=\dfrac{125}{100}\times 8\\\\=10\ \text{hours}

Hence, you will work for 10 hours.
