Here's my question or questions:
My 7th grader has a set of serious word problems once a week for homework. Last night they involved probability. I am embarrassed to say how long I and then my husband, the engineer, spent trying to figure out two of the problems. Meanwhile our son heckles us and comments about the impossibility of his math homework if even his parents can't do it.
SO...do you know a great math homework web site. I'd love a great one to go to as I see this becoming year long torture.
Or if you know how to solve the following question, I'd really like to know the answer.
If a club consists of ten members, how many different arrangements of
president, vice president, and secretary are possible?
