Answer:
0.27 = 27% probability that you receive the TOG scolarship.
Step-by-step explanation:
I am going to solve this question treating these probabilities as Venn probabilities.
I am going to say that:
Event A: TOG scolarship
Event B: VEOP scolarship
The probability that you receive the VEOP scholarship is 0.25
This means that 
Probability that you receive both scholarships is 0.15
This means that 
The probability that you get at least one of these scholarships is 0.37.
This means that 
What is the probability that you receive the TOG?
This is P(A). These measures are related by:

So

Replacing with the values in this question

0.27 = 27% probability that you receive the TOG scolarship.
