The 1/3% would equal .33% hopefully that helps at least a little
Answer:
7/11
Step-by-step explanation:
Two events are disjoint events if they cannot occur at the same time. It is given that A and B are disjointed events, so A and B cannot occur at the same time i.e. the intersection of two disjoint events will be 0.
For two disjoint events A and B:
P(A or B) = P(A) + P(B)
P(A) is given to be 4/11 and P(B) is given to be 3/11. Using these values in the equation, we get:
P(A or B) = 
Easily move nx to left and a to the right side
mx-nx=-2-a
take x common factor
x(m-n)=-2-a
divide by (m-n)
x=(-2-a)/(m-n)
that said
The answer is do it yourself m8
1/3 opposite is -1/3 less than 12
