Answer:
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Number cube:
A number cube is a dice, which has six sides, numbered 1 to 6.
P(4)
One the sides is a 4, thus:
P(not a 2)
Of the 6 sides, one is a 2, and the other 5 are not 2. So
P(3 or 5)
One sides is 3, other is 5, 1 + 1 = 2. So

Step-by-step explanation:</h2>
First of all, we need to plot the equation:
The graph of this equation is a parabola. The vertex of this parabola lies on the point (0, 1) and the x-intecepts are the points (-1, 0) and (1, 0). But the problem asks for the graph of<em> y greater than or equal to -x^2 + 1, </em>that is, the inequality:
To find this, we choose a point on the Cartesian plane, say, (0, 0) and let's take a look to the inequality:
So the region does't contain point (0, 0), therefore the graph is the one shown below.
For the equation section:
You can put 2x + 3 = 41, for the first box. In the second box, put there is one solution.
For the inequality equation:
You can put 6x + 2 < -12, in the first box. In the second box, put one solution
