Answer #1

As per the given information,

The total number of available students in a small private school (n) is 19.

The total number of selected students (k) is 6.

Need to determine the probability that the chosen 6 students are the youngest one.

The favourable cases to select 6 youngest students is 1.

First, calculate the total number of possible cases as,

So, the probability that they are the 6 youngest students is given by,

Therefore, the required probability is 0.00003685.
