1 x+2=4
2 x+3+x=7
3 find x here it is - x
6/3 = 6 divided by 3
= 2

= 2
Answer: B
Step-by-step explanation:
A = 0/360 ×π×r^2
=135/360×π×11×11
=142.55 yd^2
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)
