Question

15. Ten bands are to perform at a weekend festival. How many different ways are there to schedule their appearances?

Answer 1

Given:

Number of bands performing = 10

Number of ways to schedule 'n' distinct objects = n!

Therefore, number of ways to schedule 10 performers is given by:

`\begin{gathered} =10! \\ =10*9*8*7*6*5*4*3*2*1 \\ =3628800 \end{gathered}`

Hence, the required number of ways are 3628800
