or all possible outcomes

Flipping a coin:

Race to the Top:

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

HHH ½ * ½ * ½ = 1/8 HHT

3. PRACTICE TABLEFill in the table below, showing the 8 possible outcomes ofTossing a coin 3 times.

Outcomes Probability

HHT ½ * ½ * ½ = 1/8 HTH ½ * ½ * ½ = 1/8 HTT ½ * ½ * ½ = 1/8 THH ½ * ½ * ½ = 1/8 THT ½ * ½ * ½ = 1/8 TTH ½ * ½ * ½ = 1/8 TTT ½ * ½ * ½ = 1/8 HHT ½ * ½ * ½ = 1/8
