How many possible outcomes are there from tossing the first coin (hint check the box in the figure)
1
2
How many actual outcomes are there from tossing one coin?
1
2
If each outcome is equally likely, how would you state that as a probability?
Each are equally likely so we have to give each outcome the same value but the the sum of those values must equal 1
Each are equally likely so the probability of each is 1
Each are equally likely so we have to give each outcome the same value so it doesn't matter what value as long as they are the same
How would you put your ideas of the out come into an algebraic statement?
P(outcome 1)+P(outcome 2)=1[br]P(outcome 1=P(outcome 2)[br]P(outcome 1)+P(outcome 1)=1[br]2P(outcome 1)=1[br]P(outcome 1)=1/2[br]P(outcome 2)=1/2
How many possible outcomes are there if you toss the coin twice?
2
3
4
How would you calculate the total possible out comes?
2 X 2
2+2
Calculate the number of possible outcomes if you make three tosses?
8

6
Why do we need to calucale the total possible outcomes?
It becomes the denominator of the probability ratio
