Puzzle: The Two Tribes

An island is inhabited by two tribes. Members of one tribe always tell the truth, members of the other tribes always lie.

A missionary met two of the natives, one tall and the other short. "Are you a truth teller?" he asked the taller one.

"Ba" the tall native answered. The missionary recognised this as a native word meaning either yes or no, but he could not recall which. The short native spoke English, so the missionary asked him what his companion had said.

"He say 'yes' " replied the short native, "but him big liar!". Which tribe did each native belong to?

Suppose your role a certain dice nine times. Each time the 1-dot turns up. What is the probablility that the 1-dot will turn up again onthe next roll? Is it better than 1/6, less than 1/6 or is it still 1/6?

Independent finacial adviser - ad on CNBC

There is an advertisement by Interactive Brokers on CNBC TV. It shows an independent adviser describing her job as helping clients to monitor their investments and trading through a low cost internet platform offered by the advertiser. The adviser gives value to the clients by getting access to the suitable financial products traded on the exchange, at the lowest possible cost.

I hope that independent financial advisers will move to this business model, i.e. give value to the clients and earn a fee for their service. This fee is adequate for the time spent and is not so large as to make the client poorer off.

It is possible for a finacial adviser to make a living with this model, just as a doctor makes a living by giving medical advice for a fee.
