The probability that an industry is located in city A is 0.7; that it is located in city B is 0.4 and that it is located in A or B, or in both it is 0.8.
What is the probability that the industry is located:
a) In both cities?
b) In any of them?
Homework Answers
a)
P(A or B) = P(A) + P(B ) - P(A and B)
0.8 = 0.7 + 0.4 - P(A and B)
Therefore,
P(both A and B) = 0.3
b)
P(Any of them) = P(A or B) = 0.8
Add Answer to:
The probability that an industry is located in city A is 0.7;
that it is located...
