Answer:
0.2 = 20% probability that a student takes Spanish and engineering
Step-by-step explanation:
We solve this question treating the probabilities as Venn sets.
I am going to say that:
Event A: Student takes Spanish
Event B: Student takes Engineering.
35% of students take spainsh or engineering.
This means that 
30% of students take Spanish.
This means that 
25% of students take engineering.
This means that 
What is the probability that a student takes Spanish and engineering?
This is
.
These probabilities are related by the following formula:

So

Replacing the values

0.2 = 20% probability that a student takes Spanish and engineering
The answer is B.
In order for this chart to be true, each x and y pair must be proportional to the other ones. (in other words, each row of x and y should increase the same amount as the other ones.)
look at the first row. we can write this as 3/5 (x over y). then look at the third and fourth row. 6/10 = 3/5, and 9/15 = 3/5, so the pairs are proportional.

I am not an expert so I would not trust my answer but I am pretty sure that they are alike because if you turn them the same side well the they are both right triangles. So yes theses triangles would be alike
