Non Slip Clothes/Laundry Pegs (48 pieces, black-white/white-black) by culiclean

Product Information

Find the location of a red, if you know there's at least one red pin, but do not know in what of the holes it should be. You can find a pin by trying each of the locations. As an alternate color, we use colors we haven't tested yet. This way, we not only find the red pin but also additional information about other colors. The following is an example, if you know there's a red pin, but don't know in which one of the four holes it is. It will also give you the amount of green, yellow and pink.

When you’re venturing out to the washing line with your freshly washed clothes and towels, where do you keep your pegs? We’ve got a few peg holder solutions to make the job much easier. If you like to carry the pegs, an over the shoulder bag made specifically for the job is a great option. Just reach around for a peg and you’re done. It’s waterproof and comes with a clip so you can leave it hanging outside all the time if you like. Result 3: If there's a second white peg, you know the second color should be on the location where the red pin is.Jäger, G., Peczarski, M.: The worst case number of questions in generalized AB game with and without white-peg answers.

The next color we had information over was green - but as we know it's not the third spot, and the second and fourth spot is filled with blue & red, we know it's on the first spot. For reasons of hygiene and safety, personal grooming products, cosmetics or items of intimate clothing cannot be returned. strategy 2 (find red)) Red Yellow Yellow Yellow gives a single white peg, so while we know, red is in the first or second spot, we now know it's not in the first spot. So it's in the second location. We also know there's no yellow color Doerr, B., Winzen, C.: Playing Mastermind with constant-size memory. Theory Comput.

Note: If you know the exact amount of reds, you don't need to try the last location: if there's one red pin, and it's not in the first, second or third location, it has to be in the fourth).
