A poll is given, showing 25% are in favor of a new building project. If 2 people are chosen at random, what is the probability that exactly 1 of them favors the new building project?

(I am having difficulties with this problem)

50%

Step-by-step explanation: if two were chosen then this means that its would  be a 50 50 chance one of them is chosen.

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
