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
