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.

Answer:
$35 + $40M
Step-by-step explanation:
A cell phone company charges per month fees
$40
and an activation fee =$35
Total cost = Activation fees + ($40 × total
number of months)
So the expression for the total cost for M
months will be
$35 + $40M
152 degrees is the same as angle 5.
Because angle 5 is 152 degrees, 180-152 = 28
Angle 7 is 28 degrees
Answer:
(-∞,∞)
Step-by-step explanation:
This function is a line, with a positive slope, that never ends, so the range is negative infinity to positive infinity (non-inclusive).
