Do you use probability in your profession or real life? you most likely do. for example, the chance of rain tomorrow is 27%. we hear similar probabilities in the media all the time. similar probabilities could be found in other professions. do one of the following three: (i) find an example of probability involving "a or b" that is used in your chosen profession or real life. explain the example. are the events a and b in your example mutually exclusive? why or why not? which addition rule formula for p(a or b) applies? be sure to clearly cite the source of the information.

explained

Step-by-step explanation:

(i) Let A be the event that a student takes statistics subject as a major.

Let B be the event a student gets a job.

Two events (or propositions) are mutually exclusive or disjoint if they cannot both occur (be true). A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.

In this case, the event A and B are not mutually exclusive.

Therefore, P(A or B) = P(A U B) = P(A) + P(B) − P(A ∩ B)

add 5 subtract 1

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
