Numbered disks are placed in a box and one disk is selected at random. There are 6 red disks numbered 1 through 6, and 7 yellow disks numbered 7 through 13. In an experiment a disk is selected, the number and color noted, replaced, and then a second disk is selected. Is this an example of independence?

  • math -

    I would say so.

  • math -

    Yes, once the first disk is replaced, the event B (the selection of the second disk) does not depend on the first one.
