Idon’t have a clue how to solve this

I tried to figure it out. Im not sure if i am correct. The way that i thought of it was that each line poking out from the circle is 10%. California and Hawaii are 31% plus another 10% from the other states. so that is 41%. There is a little piece that i have no idea what % it is but taking a guess i would say about 2%. So we have 43%. so 100-43 would be 57%. That would be my best guess.

5.4%

explanation:

their acceptance rate is 5% percent and the graduation rate is 98%
