Q)

# The no. of ways in which 8 different flowers can be strung to form a garland so that 4 particular flowers are not separated is?

$\begin{array}{1 1} 4!4! \\ \frac{8!}{4!} \\ 288 \\ 5!.4! \end{array}$

• No. of ways in which $n$ different things can be arranged in a circle = $(n-1)!$
$\therefore$ they are to be considered to be one.
They can be arranged in a circle in $4!$ ways.
But these 4 flowers that are together can be arranged among themselves in $4!$ ways.
$\therefore$ The required no. of arrangements $= 4!.4!$
