We're told that



a. We want to find
. By definition of conditional probability,

By the law of total probability,

Then

(the first equality is Bayes' theorem)
b. We want to find
.

since
.
Answer:
the sum is -4
Step-by-step explanation:
Answer:
The slope is 1/3
Step-by-step explanation:
The equation is written in slope-intercept form. This is shown as y=mx+b where m is the slope and b is the y-intercept.
m is 1/3 because of this
Hope this made sense!
