Math Homework Help for 8th Grader
Got a problem to solve. I worked on this with my daughter last night, and I got an answer, but apparently I'm wrong!
There are six busybodies in town who like to share information. Whenever one of them calls another, they both know everything that the other one knew by the end of the conversation. One day, each of the six women picks up a juicy piece of gossip. What is the minimum number of phone calls required before all six of them know all six of these tidbits?
I got 10, but I guess it's not right!
Help?
