Use identity -
(a+b)² = a²+b²+2ab
(5+√3)² = 5²+(√3)² + 2(5)(√3)
= 25 + 3 + 10√3
= 28 + 10√3
= 2(14+ 5√3)
A gets 5 parts and I gets 8 parts
So 5+8=13. A will get 5/13 parts of the total
5/13*32(total)=12.3 since he can’t get .3 we round and Amir gets 12 leaving 20 for Isaac.
Answer:
Tree diagrams are most effective for complex probability calculations with multiple AND statements
Step-by-step explanation:
The given statements truths are;
A probability calculation can be calculated by using more than one model, which are dependent on the given parameters which can be either a graphical model such as a tree diagram, or an analytical model such as the systematic list model
A systematic list model is one that lists the possible outcomes of simple events
Area models are used for the representation of simple probabilities
Tree diagram models are helpful in graphically displaying complex probabilities, to aid visualization of the solution.
