Furkat [3]

The required value is 0.286 and $\dfrac{2}{7}$

Step-by-step explanation:

Since we have given that

Number of students = 7

Number of students are from Middle Georgia State College = 4

So, Probability that both of the interviewed students are from Middle Georgia State College is given by

$\dfrac{4}{7}\times \dfrac{3}{6}\\\\=\dfrac{4}{7}\times \dfrac{1}{2}\\\\=\dfrac{2}{7}\\\\=0.286$

Hence, the required value is 0.286 and $\dfrac{2}{7}$
