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.

Answer:

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)

The sum of two numbers is 17, and their difference is 29. What are the two numbers?
serious [3.7K]
X + y = 17
x - y = 29

x = 17 - y
x - y = 29

x = 17 - y
17 - y - y = 29

x = 17 - y
17 - 2y = 29

x = 17 - y 
- 2y = 29 - 17

x = 17 - y
-2y = 12

x = 17 - y 
y = -6

x = 17 - (-6)
y = -6

x = 17 + 6
y = -6

x = 23
y = -6

Here are the first four terms of an arithmetic sequence. 3 10 17 24 Find, in terms of n, an expression for the nth term of this
ollegr [7]

Answer:

a_{n} = 7n - 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = a₂ - a₁ = 10 - 3 = 7 , thus

a_{n} = 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4
