Answer:

The probability that they are the three youngest students is 0.002197.

Step-by-step explanation:

If 3 students are randomly selected from 15 available students, the probability that they are the three youngest students = 1 / 15C3

$15C3=\frac{15!}{3!12!}$

= 455

= $\frac{1}{455}$

= 0.002197
