Answer:
uh. Yeah totally
Step-by-step explanation:
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.

SOLUTION :-
AREA of sector = ( ∆/360° ) × πr²
∆ = given angle , r = radius
hence ,
AREA of sector for given angle
= ( 120°/360° ) × π 12² mi²
= ⅓ × π × 144 = 150.79 mi² = 151 mi² ( rounded off )
