First, start of by saying what the probability of getting a 4 is, which is 1/6.
Now, this means the probability of not getting a 4 is 1-(1/6)=(5/6), since the total probability is 1.
After doing this, you should think about what it means to only get 4 on the last trial, the 4th trial. It means that the probabilities of the 1st, 2nd, and 3rd trial were (5/6) each. The 4th trial had a probability of (1/6). So the probability would be calculated as following: (
=
. You can use a calculator or your computer to find out that the probability is 125/1296.

Answer:
- A. There is a line symmetry at x=1.5
- D. There are x- intercepts at (-1,0) and (4,0)
Step-by-step explanation:
The average of x-coordinates corresponding to the same F(x) value is 1.5. That is ...
(-2+5)/2 = (-1+4)/2 = (0+3)/2 = 1.5
The values in the table appear to be symmetrical about x=1.5, so that is a line of symmetry.
__
The x-intercept points are those points where F(x) = 0: (-1, 0) and (4, 0).
__
The y-intercept is (0, -4), not (-4, 0).
On the interval [0, 5] the function is both decreasing and increasing.
