Answer:

Option (C)

Step-by-step explanation:

From the circle graph attached,

14158428 students have been divided into the sectors of a circle which represent the most important problems for the high school teenagers.

Each sector corresponds the percent of different problem.

Red sector (22% of the total students) represents the most important problem of drugs.

14158428 students ≈ 14000000

22% ≈ 20%

Now 20% of 14000000 high school students = 14000000× $\frac{20}{100}$

= 2800000

Therefore, Option (C) will be the answer.

$P=\frac{5!}{6!}=0.1667$
