Math folks,
Can someone tell me what command I would use to pick out sublists
which contain just one "1"?
For example, if I have the following list,
{{1,2}, {1,3}, {2,3}, {2,1}, {1,1,2}, {1,2,2}, {2,1}},
I would like to just pull the terms,
{{1,2}, {1,3}, {2,1}, {1,2,2}, {2,1}}.
Can someone help? Thanks, Diana M.
