The following data represents the frequency distribution of 20 observations:
Then its mean deviation about the mean is:
The following data represents the frequency distribution of 20 observations:
Then its mean deviation about the mean is:
Show Hint
To find the mean deviation, first determine the mean and use absolute deviations multiplied by frequencies. Don’t forget to verify given total frequency.

- For three events \( A, B, \) and \( C \) of a sample space, if \[ P(\text{exactly one of A or B occurs}) = P(\text{exactly one of B or C occurs}) = P(\text{exactly one of C or A occurs}) = \frac{1}{4} \] and the probability that all three events occur simultaneously is \( \frac{1}{16} \), then the probability that at least one of the events occurs is

- On every evening, a student either watches TV or reads a book. The probability of watching TV is \( \frac{4}{5} \). If he watches TV, the probability that he will fall asleep is \( \frac{3}{4} \), and it is \( \frac{1}{4} \) when he reads a book. If the student is found to be asleep on an evening, the probability that he watched the TV is:
