The same could probably be said for any of my eight solutions if similar constraints were applied to them.

None of my solutions fit your constraints...

We must discern the following 4 cases for A and B:

1) They make the same forecast and both are right: Probability P = 4/5*8/9 = 32/45

2) Same forecast and both are wrong: - P = 1/5*1/9 = 1/45

3) Different forecasts and A is right: P = 4/5*1/9 = 4/45

4) Different forecasts and B is right: P = 1/5*8/9 = 8/45In our case, we have A and B give different forecasts. In such cases, A is right with overall probability 4/45, while B is right with overall probability 8/45, that is double (that is, A: 1/3 while B: 2/3).

We are asking for the probability that it rains tomorrow, that is, the probability that B is right. I would therefore say that this is 2/3.

What do you think?You are telling same thing as Relentless but have put the value wrong.

3) must be 4/5*1/10 and

4) 1/5 *9/10

Both correct!

My HP 32SII (below), working 'perfectly well' again! I must've walked off with it, and the refund! I'll have to 'pay' the shop a visit...

Consider an integer x. If we add 30, then the result is a perfect square. If we subtract 30, the result is also a perfect square. How many such integers are there?"

Let x be the number.

Can't think of anything so far!!

Anyway, I have seen both the English dubbed and captioned versions elsewhere (but I don't recall where), and the YouTube version will do for me if I need to refer to the movie again, even though the top and bottom are cut off.

I guess we'll never really know the correct answer to Kaito's puzzle (and hence yours), but I favour my reasoning in post #7 for both puzzles.

1. Make a promise

2. Never fulfill that promise, and

3. Never break that promise either.

Tis one of many fun things playing around with anything infinite can get you.
