Probability Distribution
Hello. I need help towards this one problem only. It tends to be confusing to me. Please can anybody help me?
Determine whether a probability distribution is given. In those cases where a probability distribution is not described, identify the requirements that are not satisfied. In those cases where a probability distribution is described, find its means and standard deviation.
1.Brand. In a study of brand recognition of Sony, groups of four consumers are interview. If x is the number of people in the group who recognize the Sony brand name, then x can be 0, 1, 2, 3, or 4, and the corresponding probabilities are 0.0016, 0.0250, 0.1432, 0.3892, and 0.4096. Is it unusual to randomly select four consumers and fin that none of them recognize the brand name of Sony?
