Because you are negleting the order of birth. You are counting, for example, "Older boy on Monday, younger boy on Tuesday" and "Younger boy on Monday, older boy on Tuesday" as the same event and they are not.

The correct enumeration of events are as follows:

If older boy is born on tuesday:

7 possibilities of younger girls
7 possibilities of younger boys

If older boy is not born on Tuesday

7 possibilities of younger girls
6 possibilities of younger boys (because you have been told that at least one boy was born on tuesday)

There are 27 total possible events, 13 of which are both boys.

Comment Article is misleading on primary use (Score 3, Informative) 179

The article is misleading with regard to the primary use of this device. The device was developed for military use in urban combat situations.

EMMDAR: ElectroMagnetic Motion-Detection And Ranging

It was developed because infantry were holding up standard handheld mine detectors (AN/PSS-14) that use ground penetrating radar against walls trying to determine threat levels in neighbouring buildings or rooms. Troops would then interpret the audio tones to determine rooms contents.

This device simply makes that technology smaller and more accessible and includes DSP algorithms to display potential threats (i.e. movement) on a graphical display.

Other common uses for this device is search and rescue, both military and civilian. Of course the FBI and SWAT is going to want this technology. Any time law enforcement is going to assualt a building, this device is going to prove invaluable in saving lives.

Nobody is going to pratically use this device for random checking of homes.

Comment Re:No cost cutting in manufacturing? (Score 1) 557

Charging a premium for a high quality product does not imply a disregard for cost-cutting. What you describe is a company who markets products with a variety of cost-quality trade offs. Every one of those product lines will try to reduce manufacturing cost. To claim otherwise is just rediculous. Do you think BMW, who offer premium price, high quality products have not always tried to reduce manufacturing costs? Nothing has changed in 16 years.
