Robert says that if you toss three coins you get 3H (#Heads), 2H (2 Heads), 1 H (1 Head), or OH ( 0Heads), so the probability of getting three heads is 1/4. How do you respond?

  • Probabiity -

    This is not geometry.

    The probability of getting a head on any one toss by chance = 1/2

    The probability of all events occurring is found by multiplying the probabilities of the individual events.

    1/2 * 1/2 * 1/2 = ?
