U8-Probability Practice ( Set notation- compound Prob)

Front

What is the definition of probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What does the symbol ∪ represent in set theory?

Back

The symbol ∪ represents the union of two sets, which includes all elements that are in either set.

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated as: P(E) = Number of favorable outcomes / Total number of outcomes.

Front

What is a compound event in probability?

Back

A compound event is an event that consists of two or more simple events.

Front

What does the symbol ∩ represent in set theory?

Back

The symbol ∩ represents the intersection of two sets, which includes all elements that are common to both sets.

Front

How do you calculate the probability of independent events?

Back

For independent events, the probability of both events occurring is the product of their individual probabilities: P(A and B) = P(A) × P(B).

Front

What is the difference between a finite set and an infinite set?

Back

A finite set has a limited number of elements, while an infinite set has an unlimited number of elements.

Front

What is the complement of a set?

Back

The complement of a set A includes all elements in the universal set that are not in A.

Front

What is the probability of drawing a face card from a standard deck of 52 cards?

Back

The probability is 12 out of 52, since there are 12 face cards (Jack, Queen, King) in the deck.
