Problem 1: Football and Handball Teams
In an institute with equal numbers of students, there are football teams (11 players) and handball teams (7 players).
- Suppose it is known that in a randomly chosen team, no two students were born on the same day of the week. How much uncertainty exists about the sport played by the team? Assume there are exactly 52 weeks in a year.
- Repeat the above if it is known that the team consists of students who were born on the same day of the week.
Solution
- None. In the

1 – What is the easiest way to protect an intelligent machine?
A: The easiest way to protect an intelligent machine is not using any physical protection, but the machine design or operation so that the dangerous parts are placed where no one is exposed to danger

Phonetics of the Standard
Phonetics of the Standard encompasses the phonic traits that are common to the vast majority of speakers of a language. There are phonic features that depend on context, called allophones. The phonemes that accompany a particular phoneme will influence its pronunciation.
Phonemes
Phonemes are the ideal model of meaningless minimum sound units. They are the materialization

Newspaper Structure
Sections
All newspapers are divided into sections. They always start with the cover, including the head (the most important headline), photographs of the day, and calls (small headlines highlighting notable news inside). These calls, displayed on the first page, always include the page number of the corresponding article. Advertising appears on the cover and inside the newspaper, as it is the primary revenue source for publications.
Inside, the newspaper is divided into sections

Functioning
Rotor (Inductor)
The rotor, fed with DC, creates a magnetic field. In a salient pole machine, this field is considered sinusoidal. Rotating the rotor creates a revolving sinusoidal field.
Stator (Armature)
The stator has a distribution similar to an induction machine. The rotating magnetic field induces a voltage in each stator phase. These voltages are displaced, forming a balanced three-phase system.
Load and Field Interaction
When a balanced

3.1 Motherboard
The motherboard, also known as the mainboard, is the central component of a computer. It connects almost all devices, enabling them to function correctly. The motherboard determines the computer’s capacity, compatible components, and potential for future expansion.
The motherboard is made of synthetic material with printed circuits, a set of chips, and various connectors and sockets.
