S = {H,T}
S = {2,3,4,5,6,7,8,9,10,11,12}
1. PRACTICE SET NOTATIONOn a separate piece of paper
What is the sample space for the genders in our classroom?
What is the sample space for high schools in Iron County?
S = {M,F} S = {Canyon View, Cedar, Parowan}
2. PRACTICE TREE DIAGRAMCopy the drawing below. Show the sample space of flipping a coin two times
H H ½ ½ ½ T H ½ ½ T ½ T
3. PRACTICE TABLEFill in the table below, showing the 8 possible outcomes ofTossing a coin 3 times.
Outcomes Probability
