WHAT DO YOU EXPECT?
1.2 Finding More Probabilities
Learning Target: I will conduct an experiment and write
probabilities of possible outcomes as fractions.
HW: Complete the WDYE Investigation 1 Pg.5 and
Correct with the Zaption video: WDYE 1.2
Warm Up:
1) Is it possible to toss a coin 20 times and
have it land heads up 20 times?
2) Is this likely? Explain.
Conduct your own experiment:
4. Which of the cup’s landing positions should
Kalvin use to represent Cocoa Blast?
_____________
Explain:
Class Data:
Ends
For what fraction of our class
tosses did the cup land on one of
its ends? ________
What percent is this? ________
5. Based on our class data, would
you change your answers to the
precious questions?
3. Do the landing positions end
and side have the same chance
of occurring? ________
If not, which is more likely? ____
Explain:
4. Which of the cup’s landing
positions should Kalvin use to
represent Cocoa Blast? ______
Explain:
D. Kalvin’s mother agrees to let him use a cup to decide his
cereal each morning.
On the first morning, the cup lands on its end. On the
second morning, it lands on its side.
Kalvin says, “This cup isn’t any better than the coin. It lands
on an end 50% of the time!”
Do you agree or disagree with Kalvin? Explain.
Two trials are not enough to give a good
estimate of chances … Kalvin needs to toss the
paper cup many times to make a good estimate.
