Really, there is a 100% that you will grab A shape, but if you wanna get technical...
25% for the circles, 15% for triangles, 35% for squares ,and 25% for rectangles.
It's kind of like grading a test.
1 count up the questions (shapes in this case)
5 circles + 3 triangles + 7 squares + 5 rectangles = 20 shapes
Amount correct (Amount of each shape) ÷ How many questions (Shapes)
(circles) 5÷20 = 0.25
(3÷20 = 0.15

Answer:
AC = 23
BD = 23
Step-by-step explanation:
ABCD is a rectangle,
AC and BD are its diagonals.
Diagonals of a rectangle are congruent.
Therefore,
AC = BD
7x - 40 = 2x + 5
7x - 2x = 5 + 40
5x = 45
x = 45/5
x = 9
BD = 2x + 5 = 2*9 + 5 = 18 + 5 = 23
AC = 7x - 40 = 7*9 - 40 = 63 - 40 = 23
