Answer: The required probability is $\dfrac{3}{14}$

Step-by-step explanation:

Since we have given that

Number of boys = 5

Number of girls = 3

Total number = 8

President and vice president should be girl.

So, the probability of getting a girl president and girl vice president would be :

$\dfrac{^3C_1\times ^2C_1}{^8C_2}\\\\=\dfrac{3\times 2}{28}\\\\=\dfrac{3}{14}$

Hence, the required probability is $\dfrac{3}{14}$
