Answer:
Proved, 
P(A∪B)=0.72 
Step-by-step explanation:
Sue travels by bus or walks when she visits the shops. 
Probability( catch the bus to the shop ), P(A) = 0.4
Probability( catch the bus from the shop ), P(B) = 0.7
Both A and B are independent events. 
Therefore, 
P(A∩B) = 0.4×0.7 
            = 0.28
Probability Sue walks one way = 1 - P(A∩B)
                                                    = 1 - 0.28
                                                    = 0.72
Hence, the probability that Sue walks at one way is 0.72 
 
        
             
        
        
        
M is equal to 6 because 6 times 2 would equal 12
        
             
        
        
        
Answer:
I think that she is correct because the output would be 3. sorry if I am wrong.

Answer:
a
Step-by-step explanation:
 
        
                    
             
        
        
        
 Y = mx + b
m is the gradient, otherwise known as slope
b is known as the y-intercept
So 3y = 4x + 6
Divide both sides by 3 to isolate y.
y = (4/3)x + 2
The gradient is 4/3
The y-intercept is 2
