In a bag there are 12 blue sweets, 13 red sweets and 16 yellow sweets. A sweet is picked at random. What is the probability (as a percentage) that the sweet is:
a) Not blue?

(23*2)-12=x     x=34

step-by-step explanation:

can i see the following ?

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

1. perpendicular

2. parallel

3. perpendicular
