Anumber from 8 to 15 is drawn from a bag at random. what is the theoretical probability of drawing the number 12

Step-by-step explanation:

In order to calcilate the probability of something to happen we need to knwo the total number of outcomes possible, in this case from 8 to 15, there are 8 numbers that can be drawn from the bag, if we want to draw only the number 12, there is only 1 possibility to draw it from the bag, then we just divide it:

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.
