Short Answer 0.8

Remark
The total number of possible draws is
3 Blue + 2 Red + 5 silver = 10
There are two ways of solving this, both of which will be used later on.

Method 1
If you don't draw a read paper clip, that means you will draw a silver or blue paper clip.
[tex] \frac{Silver + blue}{10} = \frac{3 + 5}{10} = \frac{8}{10} = \text{0.8} [/tex]

Method Two
The other way is to draw a red one and take that probability away from 1. 
P(red) = [tex] \frac{2}{10} = \text{0.2} [/tex]
1 - 0.2 = 0.8 Same answer.

8/10 you have to see what they have in common which would be a 2.

8 divided by 2 is 4

10 divided by 2 is 5

8/10 simplified = 4/5

ANSWER IS 4/5
