Answer:

Addition law of probability  define that probability of two event  is total sum of probability of any event subtract the probability of both events

There are two rules  in addition law:

Addition law 1 -  when both event are mutually exclusive, then probability of either event is the sum of each event probability.

P( A or B) = P(A) +P(B)

Addition law 2 -  when both events are non mutually exclusive then there in addition to the individual probability there is some overlap .

P( A or B) = P(A) +P(B) - P(A and B)

Answer:

A. y=-8.583x+475.215

Step-by-step explanation:

We are given,

The table representing the closing prices of stock for the last five days is,

Day                         Value

1                                472.08

2                               454.26

4                                439.49

5                                436.55

Using the linear regression calculator, we have that,

<h3>The linear equation that best fits the data is y=-8.583x+475.215</h3>

Thus, option A is correct.
