Question

4 boys and 2 girls occupy seats in a row at random. Then the probability that the two girls occupy seats side by side is

• (A) 1/2
• (B) 1/4
• (C) 1/3
• (D) 1/6

Answer 1

The Correct Option is C

Explanation:
$$\begin{array}{l}n(e)=\lfloor 5\lfloor 2\\ n(s)=\lfloor 6\\ p=\frac{\lfloor 5\cdot \lfloor 2}{\lfloor 6}=\frac{2}{6}=\frac{1}{3}\end{array}$$
