Answered by Steve
hmm. isn't "blonde hair and brown eyes" the same as "brown eyes and blonde hair" ?
Answered by Helena
It is saying that the whole class had either brown eyes or blonde hair. They are saying out of all the blonde haired students, 1/4 have blonde hair AND brown eyes. and it is saying out of all brown eyed students, 1/3 have brown eyes and blonde hair.
