The probability distribution of a random discrete variable is given
| X | -1 | 0 | 1 | 2 | 3 |
|---|---|---|---|---|---|
| P(X) | 0.1 | p | 0.3 | q | r |
If it is known that P(X=1) is the mean of P(X=0) and P(X=2).
Then the value of r is :

If f(x) = 2x + 3, then f⁻¹(x) is:
A relation R in the set A = {1, 2,3, 4} is given by R = {(1,1), (2,2), (1,2), (2,3), (3,4), (4,4), (1,3), (2,4), (1,4)} is
If $P(A) = \frac{3}{5}$, $P(B) = \frac{1}{2}$ and $P(A \cap B) = \frac{1}{4}$, then $P(\overline{A} | \overline{B})$ is
If corner points of the bounded feasible region are (0, 0), (3, 0) and (0, 3) and objective function is $z = 4x + 7y$, then the maximum value of $z$ is
The maximum value of a LPP $z = 3x + 4y$ subject to the constraints: $x + y \leq 6$, $x \geq 0$, $y \geq 0$ is:
