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:
Step-by-step explanation:
hello :
note :
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1= -3 y_1= -2 m= 1/2(parallel means same slope)
an equation in the point-slope form is : y +2 = 1/2(x+3)
Answer:
Slope = - 1
y-intercept = 2
