PLEASE HELP!
15 POINTS

Answer 1

The answer is c because there is 13 shapes in total and there is 8 shapes that are not squares

Answer 2

C) P =
`(8)/(13)`

Explanation:

Square: 5

Triangle: 2

Ovals: 2

Circles: 4

Using formula of probability:

Probability =
`(Favourable Outcomes)/(Total Outcomes)` ----- 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 =
`(8)/(13)`
