A textbook has 428 numbered pages, starting with 1. You are equally likely to stop on any of the pages if you flip through the book randomly.

If you repeat this experiment `50` times, about how many times do you expect to turn to an even-numbered page?

Explanation:

There are 428 pages, starting with 1. So we have the set 1,2,3,...,427,428.

The set of even numbers is 2,4,6,...,426,428 which represents half of the previous set mentioned. It might help to look at a smaller set like {1,2,3,4} and note that the evens make up half of this and the odds make up the other half.

So the probability of landing on an even page is 1/2 = 0.5; multiply that with the number of experiments done to get (1/2)*50 = 25 which is the number of times we expect to land on an even-numbered page.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
