GCSE Secondary Maths Age 13-17 - Probability & Statistics: Venn Diagrams - Explained

The video tutorial explains Venn diagrams and set theory concepts, including union, intersection, and complement of sets. It guides through calculating the union of sets A and B, finding the intersection, and determining the probability of a number being in the complement of set A. The tutorial emphasizes understanding these concepts to solve related problems effectively.

What does the union of two sets represent?

• Elements in the universal set

• Elements not in either set

• All elements from both sets without repetition

• Elements common to both sets

Which numbers are in the intersection of set A and set B?

• 15 and 18

• 14 and 16

• 12 and 18

• 10 and 14

What does the complement of a set represent?

• Elements in the universal set

• Elements in both sets

• Elements not in the set

• Elements in the set

How many numbers are not in set A?

• 3

• 5

• 7

• 10

What is the probability of selecting a number not in set A?

• 3 out of 10

• 5 out of 10

• 7 out of 10

• 10 out of 10
