Your teacher has a large box containing an equal number of red and blue folders. There are 24 students in your class. The teacher passes out folders at random. Ten students receive a red folder. Compare the experimental probability of recieving a red folder with the theoretical probability of recieving a red folder.

Please help! I'm so confused!

  • Math -

    half are red so p = 1/2 = .5

    theory = (1/2)(24) = 12 students get red

    experiment = (p exp) (24) = 10
    p exp = 10/24 = .417 instead of 0.5

    Thanks so much! :)
