In this experiment, you will draw balls one at a time from a box and, after each draw, estimate the probability that the current box is the Blue Box.

The two boxes:

Blue Box
๐Ÿ”ต๐Ÿ”ต๐Ÿ”ต๐Ÿ”ต๐Ÿ”ต
๐Ÿ”ต๐Ÿ”ด๐Ÿ”ด๐Ÿ”ด๐Ÿ”ด
60% Blue / 40% Red
Red Box
๐Ÿ”ด๐Ÿ”ด๐Ÿ”ด๐Ÿ”ด๐Ÿ”ด
๐Ÿ”ด๐Ÿ”ต๐Ÿ”ต๐Ÿ”ต๐Ÿ”ต
60% Red / 40% Blue

How the box changes:

Blue Box Red Box 20% 20% 80% 80%

After each round, the box may change colour.

The current box remains the same colour with probability 20%,

and switches to the other colour with probability 80%.

Your task:

Both the ball counts and the transition probabilities are known to you throughout the task. After observing each ball, you will be asked to report a number between 0 and 100 representing your percent belief that the box just drawn from is the Blue Box.

Your response should take into account both the colour of the ball you just observed and the possibility that the box may have switched since the previous draw.

At the start of the experiment, each box is equally likely to be drawn.
