A spinner has 2 blue spaces, 5 yellow spaces, and 1 orange space. If the spinner is spun once, what is the theoretical probability of the spinner NOT stopping on orange?

Y=4x^2+x-1 solve using quadratic formula

Compare these two waves: the blue and orange waves have the same pitch, but the blue wave is louder. the blue and orange waves have the same volume, but the blue wave has a higher pitch. the orange wave has a higher pitch, but the blue wave is louder. the blue wave has a higher pitch, but the orange wave is louder.
