It would be 5 months until the price for the notebook computer would be the same. Here are the steps to solving the problem:

1. Step up the equation, 200 + 10x = 100 + 30x
2. Subtract 100 from both sides and Subtract 10 from both sides,
100 - 200 =  10x + 30x, 100 = 20x
3. Solve for x, 100/20 = 20x/20, x= 5

Let R be the event that a randomly chosen person lives in the city of Raleigh. Let O be the event that a randomly chosen person
Anit [1.1K]

Answer:

P(O|R)

Step-by-step explanation:

The conditional probability notation of two events A and B can be written as either P(A|B) or P(B|A).

The '|' sign is read as 'given'. So, P(A|B) is read as the probability of event A given event B which implies that it is the probability that event A will occur given that event B has already occurred.

In the question,

Event R = Person lives in the city of Raleigh

Event O = Person is over 50 years old

The statement says, 'given that the person lives in Raleigh' which means that event R has already occurred and we need to find the probability of event O (the randomly chosen person is over 50 years old).

Hence, this statement can be given in conditional probability notation as

P(O|R)
