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 square is not chosen first). ! 15 points

C) P =

Step-by-step explanation:

Square: 5

Triangle: 2

Ovals: 2

Circles: 4

Using formula of probability:

Probability = ----- 1

Total Outcomes: 5 + 2 + 2 + 4 = 13

Favourable Outcomes: 2 + 2 + 4 = 8 (Excluding 5 squares)

A sqaure is not chosen first, which means that any shape of the rest of 8 shapes can be chosen

so eq 1 becomes

P =

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
