Note the following:

  • The formula for the combination for the selection of the \mathrm{x} items from the \mathrm{y}different items is \mathrm{=^{y}C_{x}=\frac{y!}{x!(y-x)!}}

  • The combination for the selection of the none or more items from the \mathrm{n}identical items is \mathrm{=n+1}

From the available data, the following is evident.

  • The combination for the selection of the none or more Banarasi Silk is =16+1=17

  • The combination for the selection of the none or more Kerala cotton is =5+1=6

  • The combination for the selection of the none or more , Zadhosi is=6+1=7

  • The combination for the selection of the none or more , Bangalore silk is=9+1=10

Therefore, the required combination is

=17\times6\times7\times10

=7140
