The choir consists of 5 boys and 6 girls. In how many ways can the singers be arranged in a row, so that all the boys are together? (assume all members of the group are uniform and combinations within the group do not matter).
I couldnt figure out how to do this via combinatorics equations so I just wrote it down.
BBBBBGGGGGG. Had bout 30sec left and it dawned on me that all we have to realize is that we can arrange it
GBBBBBGGGGG, GGBBBBBGGGG etc... I count 7. U dont have to write all of these out just realize u can have 5 inbetween G's and 2 on the outside.
