the one at the end is rounded down... making the decimal 0.86
Making it 86%
Answer:
Step-by-step explanation:
Given that the probability that an American company will open a location in Shanghai, China is 0.7.
The probability that it will open a location in Beijing, China is 0.4.
The probability that it will open a location in either Shanghai or Beijing or both is 0.8.
the probability that the company will open a location in:
(a) both Shanghai and Beijing :

P(both) = 0.3
(using addition theory of probability for union of sets)
(b) neither Shanghai nor Beijing
= 1- P(AUB)

(c) Beijing but not in Shanghai?
P(Beiging)_P(both) = 
(d) Shanghai given that it opens a location in Beijing
=P(Both)/P(Beijing) = 
Answer:
y = -51
Step-by-step explanation:
y - (-10) = -41
Subtracting a negative number: - (-10) is the same as just adding a positive number + 10, so we'll use this to simplify the expression.
y + 10 = -41
Now, we can subtract 10 from both sides of the equation in order to isolate y.
10 - 10 = 0
-41 - 10 = -51
This means the equation is now:
y = -51
Let's check this answer:
Input -51 as y:
-51 - (-10) = -41
-41 = -41
It works!
This means y = -51 is the answer!
