Using it's concept, the probabilities are given as follows:
19. A. 1/3.
20. F. 1/6.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:
p = 4/12 = 1/3.
Which means that option A is correct.
2 papers have a score greater than 12, hence the probability in item 20 is given by:
p = 2/12 = 1/6.
Which means that option F is correct.

Answer:</h3>

<h3>
Step-by-step explanation:</h3>
In this question, it's asking you to put the numbers that were given from <em>least </em>to <em>greatest.</em>
Our given numbers are:
Now, lets sort them out.
We know that negative numbers would be the least. Sicne there's only one negative number, we would put that first because it's the least out of the numbers.
would go next. To make it easier, we can turn it into a decimal.
when you divide.
0.35 will go next. This would be bigger than 0.15, but lower than the next number.
would go last, due to the fact that it's the greatest.
is the same as 1.75
When you put them in order, you should get

So the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64
