The maximum value of the objective function $Z=ax+by$ in a LPP always occurs at only one corner point of the feasible region.

If the feasible region for a LPP is unbounded, maximum or minimum of the objective function $Z=ax+by$  may or may not exist.

The feasible region for an LPP is always a __________ polygon.

A corner point of a feasible region is a point in the region which is the __________ of two boundary lines.

A feasible region of a system of linear inequalities is said to be __________ if it can be enclosed within a circle.

In a LPP, if the objective function $Z=ax+by$ has the same maximum value on two corner points of the feasible region, then every point on the line segment joining these two points gives the same __________ value.

If the feasible region for a LPP is __________, then the optimal value of the objective function $Z=ax+by$ may or may not exist.

In a LPP, the objective function is always __________.

In a LPP, the linear inequalities or restrictions on the variables are called __________.

The probability of a man hitting a target is $\frac{1}{10}$ . The least number of shots required, so that the probability of his hitting the target at least once is greater than $\frac{1}{4}$ , is(Probability)
