Chapter 11 Summary-Probability
- 11-01 Sample Spaces
- PROBABILITY
- A chance of occurring
- Can be:
- A decimal
- A fraction
- A percentage
- EXPERIMENT
- Is a situation involving chance that
leads to results called outcomes
- TRIAL
- Is one go or run of the experiment
- SAMPLE SPACE
- Is the set of all possible outcomes
- RANDOM EXPERIMENT
- Every possible outcome has the same chance of
occurring (otherwise the experiment is said to be biased)
- In curvy BRACKETS
- 11-02 Probability
- P (E)
- = (number of favourable outcomes) /
(total number of outcomes)
- 11-03 The range of probability
- 11-04 Experimental Probability
- EXPERIEMENTAL PROBABILITY
- Is calculated based on the
result of the experiment
- THEORETICAL PROBABILITY
- Theoretical probability is calculated
to try predict what the result will be
( experiment has not occurred yet.)
- P (E)
- = (number of times that events have happened) /
(total number of trials)
- 11-05 Complementary Events
- COMPLEMENTARY EVENTS
- Are opposite events
- events + it's complement = all possible evnts
- P (not E) = 1 - P(event)
