A school has 10 iPads, 20 Chromebooks, and 5 laptop computers in their technology loaner supply closet. For each part below, assume all devices are available (so the supply does not change in part B based on what happened in part A, and so on. You begin with all 35 devices in each question.) What is the probability of selecting two devices and not having only Chromebooks? In other words, what is the chance you have at least one device that is not a Chromebook? Round the answer to 4 digits after the decimal point.

I answered the first three parts of this question but got stuck on this one. Any help is appreciated!

What value of x will make the triangles similar by the sss similarity theorem?

Find the combined area of the triangles. click on the answer until the correct answer is showing. possible answers: a = 4 pi - 8a = 9 pi - 9/2 √3a = 16/3 pia = 16a = 27 pi
