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).

Respuesta :

We have 13 total shapes and 7 of them meet the criteria, so the probability is:

P(Square or Triange) = [tex] \frac{7}{13} [/tex]

or about 0.3888.....
or 38.88%

Total shapes:
5 + 2 + 2 + 4 = 13
Probability of triangle: 2/13
Probability of square: 5/13
Probability of triangle or square: 2/ 13 + 5/13
= 7/13
