A box of chocolates contains 18 chocolate squares. Ten of the squares are milk chocolate, 5 are dark chocolate, and 3 are white chocolate. If Christina randomly chooses a chocolate out of the box, what is the probability of her choosing a white chocolate square (fractions)

3:26

Step-by-step explanation:

so  You put the 3 first since its aids What is the probabloty Choosing A WHITE CHOCOLATE. then you just add up 3 +5+18.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
