Which of the following best describes a chord?

Option A: A chord is a line segment that has both endpoints on a circle.

Step-by-step explanation:

A chord of a circle is a line segment whose endpoints both lie on the circle.

In general a chord is a line segment that connects two distinct points on a circle. Its also called a secant in a circle, that intersects the circle at exactly two points.

Here, option A is correct.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
