You need to select the bc package for installation from the "Select Packages" window.
By default setup installs only base category that is ~ 50 packages, while the full availability is ~ 4000.

Run the Cygwin setup.exe and search for "bc" in the "Math" category, click on it and hit Next to install.

I believe that bc is not installed by default on Cygwin, and you will need to install it manually. This link might help you.
