- - - - Does sample pulled from the jar match the makeup of the population?
  - - - Probability includes uncertainty, because it is not impossible to pull a white marble, just less likely
- - - - Requirement 2 for this formula: Independent Random Sampling also called Random Sampling or Random Sampling with Replacement or If more than one individual is being selected, the probabilities must stay constant from one selection to the next.
        
        Independent: probability for selecting any individual is not influenced byt he individuals already selected for the sample
        
        Requirements assure no bias in selection. Each individual has the same probability p=1
        
        There are other types of sampling techniques.
        
        Random sampling without replacement.
    - - Random sampling: each individual in the population has an equal chance of being selected.
        
        Selecting a sample through this process is called a Simple Random Sample
        
        .
        
        For example: the lottery does not give an equal chance of winning. Flipping a head on a coin does.
