What is the probability that a randomly selected U.S. resident did not live in Idaho? Show step by step work. Round solution to the nearest thousandth.


Would it be 1/1523816 = 0.000000656??

  • Math - ,

    The probability that a randomly selected U.S. resident did live in Idaho
    = 1523816/303824640

    so the probability that a randomly selected U.S. resident did not live in Idaho
    = 1 - 1523816/303824640

    I will leave the arithmetic up to you

  • Math - ,

    1523816/303824640 = 0.005
    1 - 0.005 = 0.995 or would it be 0.990 when rounded to the nearest thousandth?

  • Math - ,

    You would have to look at the 4th decimal which you did not show.
    On my calculator, I got
    .9949 , so to the nearest thousandth that would be

    .995

  • Math - ,

    oh okay...thank you Reiny for your help :)
