B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)
Answer : 25/51
The probability of drawing two red cards without replacement is 25/102 , and the probability of drawing one red card is 1/2 .
probability(drawing a second red card, given that the first card is red)
= Probability (drawing two red cards without replacement) divide by probability (drawing a one red card)
probability(drawing a second red card, given that the first card is red)

1. Suppose that a triangle and a rectangle lie in a plane. What is the greatest number of points at which they can intersect?Answer: 6.Because one line of the triangle can intersect maximum two lines of the rectangle, which makes two intersection points.
So, the maximum number of possible intersections is when you arrange the triangles so that its three lines intersect three different lines each.
See the attached picture.
2. Suppose that a circle and a square lie in a plane. What is the greatest number of points at which they can intersect?Answer: 8.The attached figure shows a circle and a square with 8 intersection points.
That is the maximum number of points at which a circle and a square in a plane can intersect: each line of the square intersect two different points of the circle.
3. Suppose two distinct triangles lie in a plane. What is the greatest number of points at which they can intersect?Answer: 6See the image attached.
Each line of a triangle intersect one different line of the other triangle in two different points.
4. Suppose that a circle and a triangle lie in a plane. What is the least number of points at which they can intersect?Answer: 0You can draw two figures that do not intersect each other. See the picture attached.
5. Suppose two distinct squares lie in a plane. What is the least number of points at which they can intersect?
Answer: 0As you can see the figure attached you can draw two different squares which to not intersect each other.
