• Unpredictable. Random selection means that each item has an equal chance of being selected and there is no systematic bias to select one item rather than another. Coin flips are random. Knowing that one coin flip came up heads does not change the likelihood that the next coin flip will come up heads (these coin flips are said to be independent).  1
