Okay now. New question. Find the number of (m) ways in which 6 people can ride a toboggan if ONE OUT OF THREE people must drive.

M=?

PLEASE DO NOT SOLVE! Just tell me how to do the problem. You MIGHT use factorial.

  • Math -

    If you mean that the 6-person team must contain 3 drivers, then

    the driver can be selected in 3 different ways

    The remaining 5 riders can be arranged in P(5) = 5! ways

    If I have misread the problem, please clarify.

  • Math -

    I think you kind of misread it.
    I meant that there was ONE driver, although you pick 1 driver out of THREE drivers. Thank you for your time though.

  • Math -

    Can anyone answer my question?

  • Math -

    If you read carefully, I think you will find I did. 3 ways to choose the driver,
    5! ways to arrange the riders.

    thank you for your help!
