<span>A binomial distribution is the discrete probability distribution of the number of successes in a sequence of independent experiments, each asking a yes/no question, and each with an outcome that has a random variable containing single bit of information. So, an example would be A: Find the probability of selecting a red ball from a vase containing red, green, and yellow balls after selecting two yellow balls without replacement.</span>
        
             
        
        
        
Let's solve together :)
Solving for a.
First, add 56 to both sides to get this:
8ab+2a=−56b+6
Factor out variable "a". 
a(8b+2)=−56b+6
Divide both sides by 8b+2.
a = -28b+3 / 4b+1
Have a great day. :)
 
        
             
        
        
        
Answer:
It is a Cuboid
Area of the base = 12x9 
Area of the top = 12x9
Area of the right lateral faces = 9x7
Area of the left lateral faces = 9x7
Area of the front face = 12x7
Area of the rear face = 12x7
Total surface area is the sum of above (please do it yourself)
The volume = base surface Area x height
 = 12x9x7 = 756
Be reminded to put in the right unit for Area and volumn
