Using the Fundamental Counting Theorem and the probability concept, it is found that:
- There are
ways to answer all 17 questions.
probability you will get them all right.
- It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:
- A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
- The questions in part A and in part B are independent.
- For the 12 questions in part A, there are
ways to answer, hence
.
- For the 5 questions in part B, there are
ways to answer, hence
.
Then:
There are ways to answer all 17 questions.
Only one outcome in which all the guesses are correct, hence:
probability you will get them all right.

Answer:
See explanation
Step-by-step explanation:
The question is incomplete, as the diagram of coordinates of the three triangles are not given.
A general explanation is as follows:
First, record the coordinates of the corresponding points of the three triangles.
For instance; In triangles ABC, DEF and GHI; A, D and G are corresponding points.
Now, assume the coordinates are:
Point D is 4 points to the right of A;
i.e.
Hence, ABC will be moved 4 units right to lie on DEF
Similarly, point G is 3 units down of A
i.e.
Hence, ABC will be moved 3 units down to lie on GHI.
