too confusing for me man :( however they didnt teach us this yet, so im okay

Okay do it like this.

You got three boxes, they're labeled BB, RR, and BR

BB is box 1, RR is box 2, and BR is box 3.

Step 1. Pull a hat out of box 3.

Step 2. If the hat is red, then box 3 contains two red hats, so go to step 3. If it is blue, then both hats are blue, so go to step 4.

Step 3. If both hats in box 3 are red, and box 1 cannot have two blue hats, then box 1 must have one blue hat and one red hat. Therefore box 2 has two blue hats.

Step 3. If both hats in box 3 are blue, and box 2 cannot have two red hats, then box 2 must have one blue hat ando ne red hat. Therefore box 1 has two red hats.

Is that any easier?

BB RR BR

Okay, you take a hat out of BR. What color is it?

Well, the box is labeled BR, and the label is wrong.

No - the box only has one label, which is Blue and Red. All that means is that if one of the hats is blue, the other one cannot be red. So if it is blue, the other hat has to be blue too. Right?

so are you saying all boxes are either RR or BB and they are lables RB?
