One of my favorite math exercises:
Reds: 79-52 31g remaining
Cards: 71-58 33g remaining
Pitt: 69-60 33g remaining
If Reds go 15-16(.484)
Cards would have to go 23-10(.692) to tie
Pitt would have to go 25-8(.756) to tie
If Reds go 17-14(.548)
Cards would have to go 25-8(.758) to tie
Pitt would have to go 27-6(.818) to tie
If Reds go 19-12(.613)
Cards would have to go 27-6(.818) to tie
Pitt would have to go 29-4(.879) to tie
