  1. Jul 28, 2010 #1
    I have read the entire chapter in my book and have searched the internet and I still have no idea where to even begin. HELP!


    4. a.) Explain the significance of a probability of 1.0 and of a probability of 0.0.

    b.) Calculate the probability for an event to occur if 420 events have been recorded as successful for 1200 attempts.

    c.) Find the probability of throwing a "tail" if your tossing a balanced coin.

    What can you say about 4a) ? If the probability is 1, what % of the time will something happen? If it's 0, what % of the time will something happen?

    On c), what is the probability of heads or tails when you toss a coin? If you're not sure, try it. Toss the coin 100 times -- what percentage of the time is it tails?
