ANSWER:
The probability is 1/43680
STEP-BY-STEP EXPLANATION:
We have the following:
0. The probability that Morgan is chosen first = 1/16. Now there are 15 students left after this.
,1. The probability that Harmony is chosen second = 1/15. Now there are 14 students left after this.
,2. The probability that Kenny is chosen third = 1/14. Now there are 13 students left after this.
,3. The probability that Ben is chosen fourth = 1/13.
Therefore, the required probability is:
[tex]\begin{gathered} p=\frac{1}{16}\cdot\frac{1}{15}\cdot\frac{1}{14}\cdot\frac{1}{13} \\ p=\frac{1}{43680} \end{gathered}[/tex]
