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
Answer:
how once you explain or show a picture report my answer and i will answer right
Step-by-step explanation:
Answer: he can buy 3
Step-by-step explanation: divide it
Ratio means proportion, correlation, or relationship.
Eg. The ratio of brown dogs to white dogs is 6:2. This means there are 6 brown dogs and two white dogs in the group. You could also say that there are 3 times as many brown dogs as white dogs.
You can simplify a ratio. Take the example we looked at: 6:2. You could simplify that one by dividing each by the same number.
You would divide it by 2, and end up with 3:1. That still says that there are 3 times as many brown dogs as white dogs.
I hope this helps you.
