GIT Bash uses MINGW compilation of GNU tools. 
It uses only selected ones. 
You can install the whole distribution of the tools from https://www.msys2.org/ and run a command to install bc. 
And then copy some files to installation folder of Git. 

This is what you do:

1. Install before-mentioned msys2 package and run msys2 shell.
2. Install bc using the following command: pacman -S bc
3. Go to msys2 directory, for me it's C:\msys64\usr\bin
4. Copy bc.exe to your Git for Windows directory, for me this is C:\Users\\AppData\Local\Programs\Git\usr\bin
