wlad13 [49]

Answer

28 committees

Explanation:

The total number of members = 8

We want to make a committee of 2 members

We will be applying the combination concept

$\begin{gathered} \text{let n = 8 and r = 2} \\ ^nC_r\text{ = }\frac{n!}{(n\text{ - r)!r!}} \\ ^8C_2\text{ = }\frac{8!}{(8\text{ - 2)!2!}} \\ ^8C_2\text{ = }\frac{8!}{6!2!} \\ ^{8_2}C\text{ = }\frac{8\text{ x 7 x 6 x 5 x 4 x 3 x 2 x 1}}{6\text{ x 5 x 4 x 3 x 2 x 1! 2 x 1}} \\ ^{8_{}}C_2\text{ = }\frac{8\cdot\text{ 7}}{2} \\ ^{8_{}}C_2\text{ = 28 committees} \end{gathered}$

Therefore, 28 committees can be formed
