Explanation / Answer

Ewww, probabilities. It makes it a lot easier that more than onecould be on the same lane. Kim can only pick the credit card lanes. She has 4 total optionsfor lanes. The other two women (I'm guessing this was written a while agogiven that the names are all girls, usually more modern problemstry to be more politically correct) can chose any of the 7lanes. 4*7*7=196. With Kim in lane 1, there should have been 49 possibilities, sincethe other women have 7 options each or 7*7, it's good you asked ;)
