الاحتمال: مفهوم الاحتمال النظري

The video tutorial explains the concept of probability using a spinning wheel with four equal sectors, each a different color: yellow, red, green, and blue. Initially, the probability of the pointer landing on any color, including blue, is calculated as one in four. The tutorial then explores the scenario where the red sector is replaced with another blue sector, altering the probability of landing on blue to one in two. This demonstrates how changes in the number of sectors of a particular color affect the overall probability.

What is the probability of the pointer landing on the blue sector initially?

• 1/2

• 1/3

• 1/4

• 1/5

How many sectors are there on the spinning wheel?

• Three

• Two

• Five

• Four

What is the probability of the pointer landing on any given color?

• 1/3

• 1/2

• 1/4

• 1/5

If the red sector is replaced with a blue one, what is the new probability of landing on blue?

• 1/5

• 1/4

• 1/3

• 1/2

How many blue sectors are there after replacing the red sector with blue?

• Four

• One

• Two

• Three
