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
[tex]15C3=\frac{15!}{3!12!}[/tex]
= 455
= [tex]\frac{1}{455}[/tex]
= 0.002197
