Answer:

Step-by-step explanation:
Given
P(A or B)= P(B)-P(A and B)
P(A)=1/3
P(A and B)=1/8
P(A or B)= 3/4
Required
Find P(B)
To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.
This goes thus;
P(A or B) = P(B) - P(A and B) becomes

Make P(B) the subject of formula

Take L.C.M

Add fractions

From the workings above, the value of P(B) using the given equation is 
Answer:
7x+3
Step-by-step explanation:
2x+y
5x-y+3
Then you solve it by crossing out the y and adding the x’s.
7x+3
Answer:
b
Step-by-step explanation:
i just took the quiz plz mark brainliest
Length = √(y2-y1)² + (x2-x1)²
l = √(5 - 5)² + (9 + 2)²
l = √0² + 11²
l = √121
l = 11
In short, Your Answer would be 11 units
Hope this helps!
