Discuss the following questions.
In our class data, which outcomes are least likely?
Which outcomes are most likely?
Compare this to your small group data. Is it the same? If not, what makes the difference? (sample size)
♦Ask students: Which scores on a single toss are equally likely (have the same probability)?
♦Have students list the ways to get a sum of 1.
(H T T T T | T H T T T T T H T T T T T H T |
T T T T H) |
|
♦Now have students list the ways to get a sum of 4 to verify that the sums of 1 and 4 are equally likely.
(H H H H T H H H T H H H T H H H T H H H T H H H H)
Assessment Suggestion for Part A
Have students record in their journals how they determined which outcomes were most or least likely to occur.
Have students perform the steps unless otherwise indicated.
1.Discuss the difference between the probabilities that were gathered (experimental probabilities) and the probabilities that should have happened (theoretical probabilities).
2.Use the tree diagram on the activity sheet to find the expected (theoretical) probabilities and record them on the activity sheet.
