Question

Anthony is making a collage for his art class by picking shapes randomly. He has five squares, two triangles, two ovals, and four circles. Find P(a triangle or a square is chosen first).

Answer 1

So that would make the answer 7/13?

Answer 2

We have 13 total shapes and 7 of them meet the criteria, so the probability is:
\[P(SquareorTriange)=\frac{7}{13}\]
or about
0.3888.....
or
38.88%
