Fran the Fearless has a well-known act at a local 200. As part of the act, Fran handles a scary animal that she picks at random out of the Box of Terror. The following animals are in the box: 10 poisonous snakes, 5 nonpoisonous snakes, 8 poisonous spiders, and 6 nonpoisonous spiders. What is the probability that
the animal Fran picks is poisonous or is a snake?

i will pick c put check it over to be sure

step-by-step explanation:

the first one, all those points on the line just make a strait line.

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.
