Venn Diagrams and Probability

Front

What is a Venn Diagram?

Back

A Venn Diagram is a visual representation of the relationships between different sets, often using overlapping circles to show common elements.

Front

What does the shaded region in a Venn Diagram represent?

Back

The shaded region represents the elements that belong to the specified sets, such as the intersection or union of those sets.

Front

How do you convert a decimal to a percent?

Back

To convert a decimal to a percent, multiply the decimal by 100 and add a percent sign.

Front

What is the formula to find the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

If the probability of an event is 1/4, what is the percent chance?

Back

25%.

Front

What is the intersection of two sets A and B?

Back

The intersection of sets A and B, denoted as A ∩ B, is the set of elements that are common to both A and B.

Front

What is the union of two sets A and B?

Back

The union of sets A and B, denoted as A ∪ B, is the set of all elements that are in A, in B, or in both.

Front

How do you find the probability of multiple independent events occurring?

Back

To find the probability of multiple independent events occurring, multiply the probabilities of each individual event.

Front

What is a complementary event?

Back

A complementary event is the event that represents all outcomes not in the original event, often denoted as A'.

Front

If event A has a probability of 0.7, what is the probability of its complement?

Back

The probability of the complement of event A is 1 - 0.7 = 0.3.
