Answer 1

Drink | Percentage
--------------------
soft drinks | 46
milk/choc | 26
water | 12
tea | 5
other | 11 \(\Huge\ddot\smile\)

Answer 2

milk/choc and {milk, choc}. What's the difference here?

Answer 3

1. milk/chocolate milk = 26
2. The school only serves milk, chocolate milk

Two contradicting statements.

Answer 4

,,,,,more like two divergent statements.

Answer 5

I think it just means that milk and chocolate milk are considered as 1 thing in the table
So only milk, chocolate milk and water. Together thats 38% (26+12)

Answer 6

Then why the comma in the second statement?

Answer 7

Doesn't matter, both are served

Answer 8

Also, can the child in the front actually choose his drink, or are they randomly served? ;-)

Answer 9

It's kind of a bad question, but I'd go with .38 too.

Answer 10

Yes, it is a crazy question. I just wanted to make sure I wasn't going crazy!
