A cup containing 3 blue paper clips, 2 red paper clips, and 5 silver papers clips . What is the probability of not drawing a red paper Clip?

0.2

Step-by-step explanation:

The total universe consists of 3 + 2 + 5 = 10 paper clips.

2 of them are red.

The probability of drawing one is 2/10 = 0.2 or 1 chance in 5.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
