Answer: Choice C -- (0.6, 1.9)</h3>
Explanation:
Look through the table to see where f(x) and g(x) are the same value. Unfortunately this never happens for any row. However, we can get fairly close when we look at row two with f(x) = 1.8 and g(x) = 2; this input is x = 0.6
A good guess is that the midpoint of 1.8 and 2 is the y coordinate of the solution, so this is where the 1.9 comes from. You add 1.8 and 2 to get 3.8, then divide in half to get 1.9
So when x = 0.6 a good guess at the y value of the solution is y = 1.9, meaning that (0.6, 1.9) is an estimate of the solution
note: this is likely not the true solution, but it may be fairly close
There are 20 total cubes.
7/20 + 5/20 = 12/20 = probability that the cube WILL be blue or red. Can be reduced to 3/5
Therefore, the probability that the cube will NOT be blue or red is 8/20 or 2/5.
