Shouldn’t there be a total of 61 people being surveyed?The 6 won’t be in the circles but it’ll be in the diagram.Since the qn states that there’s no people with both (from what i’m assuming from the qn)We will group those with a brother in one circle and call it “A” and those with a sister as another circle and call it “B”.So the diagram should look something like this ⬇️ don’t mind my handwriting
