Estimating Probabilities

The likelihood that Han makes a free throw in basketball is 60%. The likelihood that he makes a 3-point shot is 0.345. Which event is more likely, Han making a free throw or making a 3-point shot? Explain your reasoning.

Making a free throw because 60% chance is much greater than 0.345, which equals 34.5% chance.

Define sample space

Sample space is the list of ALL possible outcomes for a chance experiment

Will I definitely get heads 5 times if I flip a coin 10 times? Why or why not?

No, probability is the expected outcome but may not actually happen. 

300

Are the two scenarios below impossible, unlikely, equally likely as not, likely, or certain?

1. Every student in this class ate macaroni and cheese this morning for breakfast. 

2. It will snow in November here in Boulder.

1. unlikely 

2. likely 

300

Define probability. What numbers must it be between?

A measure of likelihood that the event will occur

300

The more repetitions an experiments has, will the estimate of probability be more or less accurate? Why?

more

400

Define outcome

Something that can happen when you do a chance experiment
