The median of the observations 7, 8, 7, 9, 7, 14, 15, 6, 8, 14, 9,17, 15, 16 is
If the mean and mode of a data are 45 and 51 respectively then the median of the data is
The quartile deviation of the observations 80, 48, 60, 92, 50, 35, 70 is
If $$\sigma$$ is the standard deviation of the observations $$x_1, x_2, ........., x_n$$ then the standard deviation of $$5x_1 + 7, 5x_2 + 7, ......, 5x_n + 7$$ is
If two unbiased six-faced dice are thrown simultaneously then the probability that the sum is 8 with at least one die showing a prime number is
If A and B are events of a random experiment with $$P(A) = \frac{3}{8}, P(B) = \frac{1}{3}$$ and $$P(A \cap B) = \frac{1}{4}$$ then $$P(\overline{A} \cap \overline{B}) =$$
