Let random variable QQ represent the number of employees who work at a certain restaurant on a given day. The following table shows the probability distribution of the random variable QQ. Which of the following claims is best supported by the table? The most likely number of employees who work on a given day is 24. A The mean number of employees who work on a given day is equal to the median number of employees who work on a given day. B The mean number of employees who work on a given day is greater than the median number of employees who work on a given day. C The mean number of employees who work on a given day is less than the median number of employees who work on a given day. D On a given day, the number of employees who work at the restaurant occurs with equal probabilities.
