Jane chooses a number X at random from the set of numbers {1,2,3,4}, so that P(X = k) = 1/4 for k = 1,2,3,4.
She then chooses a number Y at random from the subset of numbers {X, ... , 4};
for example, if X = 3, then Y is chosen at random from {3,4}.
(i) Find the joint probability distribution of X and Y and display it in the form of a
two-way table.

answer:

c. the third graph

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
