A quality control inspector found flaws in 13 out of 150 sweaters. Find the probabillity that a sweater has a flaw. Round to nearest tenth of a %

But what if the company produces 500 sweaters, how many will NOT have flaws

  • Math...again - ,

    150 - 13 = 137 without flaws

    137 * (500/150) = 457

    this is simplistic. The chances are that around 457 do not have flaws based on our sample of 137 out of 150 flaw free. You of course can not say for sure.
