1. A set of cards has 10 cards with stars, 10 cards with squares, and 15 cards with circles. Find the probability of picking a star or a
circle. Write your answer in simplest form.

10 with squares it will give u the answer quicker in the area

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: the answer is fre sha voca do
