Probability Concepts and Definitions

The video tutorial covers the basics of probability, including sample spaces, outcomes, and events. It explains probability experiments and the concepts of complementary and disjoint events. The tutorial differentiates between empirical and classical probability, providing examples and calculations. It concludes with a discussion on subjective probability, emphasizing its non-mathematical nature.

What is a probability experiment?

• A trial with no outcome

• A trial with a certain outcome

• A trial with an uncertain outcome

• A trial with a predictable outcome

What is the collection of all possible outcomes of a probability experiment called?

• Event

• Sample Space

• Simple Event

• Outcome

What is a simple event?

• An event with uncertain outcomes

• An event with multiple outcomes

• An event with no outcomes

• An event with a single outcome

What are disjoint events?

• Events that can occur simultaneously

• Events that always occur

• Events with overlapping outcomes

• Events with no common outcomes

How is empirical probability determined?

• By using a formula

• By guessing

• By observation and experiment

• By theoretical calculation

What is classical probability?

• Probability based on past data

• Probability based on equally likely outcomes

• Probability based on intuition

• Probability based on subjective judgment

What is the probability range for any event?

• Between -100 and 100

• Between 0 and 100

• Between 0 and 1

• Between -1 and 1

What is the probability of the sample space occurring?

• 2

• 0.5

• 0

• 1

What is the sum of probabilities for complementary events?

• 2

• 0

• 0.5

• 1

What is subjective probability?

• Probability based on mathematical calculations

• Probability based on personal judgment

• Probability based on past experiments

• Probability based on theoretical models
