A card is drawn from a deck of 52 cards. What is the probability that it is a digit card? => 9 13 or 9 11 or 1 52 or 1 13..

A single card is chosen at random from a standard deck of 52 cards. What is the probability that the card chosen is a Jack? => 1 3 or 3 52 or 1 13 or 1 8..

So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize or minimize) the objective function Z, then we say that these values of x i are the optimal so..

A real number line can be used to represent the solution set of an inequation (Linear). The convention is that O (a hollow circle) marks the end of a range with a strict inequality (i.e. < or >) and (a darkened circle) marks the end of a range involving equality as well as inequality...

The velocity-time graph for uniformly accelerated rectilinear motion (motion along a straight line), a > 0, is illustrated in the figure. The velocity-time graph for a uniformly retarded motion is as shown in the figure. Here a < 0, indicating retardation or deceleration. In this sectio..
