48. A rectangle, with its vertex coordinates labeled, is graphed in the standard (x,y) coordinate plane below. A lattice point is a point with coordinates that are both integers. A lattice point inside but NOT on the rectangle will be chosen at random. What is the probability that the sum of the x-coordinate and they-coordinate of the chosen lattice point will be odd?
Your Answer is
Correct Answer is H
Explanation
The abscissa is a total of 5 integers (1 to 5); the ordinate is a total of 3 integers (1 to 3). Therefore, there are a total of 15 lattice points, the sum of horizontal and vertical coordinates is 7 odd numbers, and 8 even numbers
