.25in;mso-list:l0 level1 lfo1">· Later events may be affected by or compensate for earlier ones
.25in;mso-list:l0 level1 lfo1"> · 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.
