Uuuuuhhhhh...... what is the scale? I can tell you that you subract the number x by the numerator (the two) and the number y by the denominator (the three)
Answer:
is the expression which is equivalent to 
.
In other words:
Step-by-step explanation:
Given the expression
solving
∴ 
Thus,
Therefore, is the expression which is equivalent to .
The events A and B are not independent.
Given that,
P(A|B) = 0.4
P(A) = 0.5
P(B) = 0.8
Two events A and B are said to be independent, if P(A∩B) = P(A) P(B)
We have, P(A|B) = P(A∩B)/P(B)
Therefore, P(A∩B) = P(A|B) P(B) = 0.4 x 0.8 = 0.32
Now P(A) P(B) = 0.5 x 0.8 = 0.4
So P(A∩B) ≠ P(A)P(B)
Therefore, the events A and B are not independent.
