I hate to be asking so many questions one after another but I can't seem to figure any of them out.
Q: A field-hockey team played 7 games and won 4 of them. There were not ties.
a) How many arrangements of the 4 wins and 3 losses are possible? Is the solution 7C4? It matches the answer which is 35.
b) In how many of these arrangements would the team have at least 2 wins in a row?
I'm stumped on this one....
Thanks a lot!
