You have a hat containing 8 red chips, 4 green chips, 5 yellow chips, and 3 white chips. find the following probabilities and write the answers as simplified fractions:
(4 points each)
probability of picking a red chip?
probability of not picking a green chip?
probability of picking one chip and it is a yellow or green chip?

Step-by-step explanation:

There are 20 chips in total.

P(red) = 8/20 = 2/5

P(not green) = 16/20 = 4/5

P(yellow or green) = 9/20

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

answer: 177/8
