Short Answer 0.8RemarkThe 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 1If you don't draw a read paper clip, that means you will draw a silver or blue paper clip.
Method TwoThe other way is to draw a red one and take that probability away from 1.
P(red) =

1 - 0.2 = 0.8 Same answer.

Answer:
graph c
Step-by-step explanation:
Given
| - 2x | = 4
The absolute value function always gives a positive result, however, the expression inside can be positive or negative , that is
- 2x = 4 or - (- 2x) = 4
Solving both
- 2x = 4 ( divide both sides by - 2 )
x = - 2
or
- (- 2x) = 4
2x = 4 ( divide both sides by 2 )
x = 2
The third graph indicates x = - 2 and x = 2 on the number line
