There are many misconceptions about probability which may include the following.

• All events are equally likely
• Later events may be affected by or compensate for earlier ones
• When determining probability from statistical data, sample size is irrelevant
• Results of games of skill are unaffected by the nature of the participants
• “Lucky/Unlucky” numbers can influence random events
• In random event involving selection, results are dependent on number rather than rations
• If events are random then the results of a series of independent events are equally likely

The following statements are all incorrect. Explain the statements and the errors fully using the probability rules discussed in topic two.

1. I have flipped and unbiased coin three times and got heads, it is more likely to get tails the next time I flip it.
2. The Rovers play Mustangs. The Rovers can win, loose, or draw, so the probability that they win is 1/3.
3. I roll two dice and ad the results. The probability of getting a total of 6 is 1/12 because there are 12 different possibilities and 6 is one of them.
4. Mr. Purple has to have a major operation. 90% of the people who have this operation make a complete recovery. There is a 90% chance that Mr. Purple will make a complete recovery if he has this operation.
5. I flip two coins. The probability of getting heads and tails is 1/3 because I can get Heads and Heads, Heads and Tails, or Tails and Tails.
6. 13 is an unlucky number so you are less likely to win raffles with ticket number 13 than with a different dumber.

A researcher randomly assigns 33 subjects to one of three groups. Group 1 receives technical dietary information interactively from an on-line website. Group 2 receives the same information from a nurse practitioner, while Group 3 receives the information from a video tape made by the same nurse practitioner.

The researcher looked at three different ratings of the presentation; difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation. In particular, the researcher is interested in whether the interactive website is superior because that is the most cost-effective way of delivering the information.
