Answer:

The probability is $P(Z) = 0.0064$

Step-by-step explanation:

From the question we are told that

The number of members is n = 15

Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

$K = ^{n}C_2 * 2!$

Here C stands for combination hence we will be making use of the combination functionality in our calculator

$K = ^{15}C_2 * 2 * 1$

=> $K = 78 * 2 * 1$

=> $K = 156$

Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1

Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

$P(Z) = \frac{m}{K}$
