Exam points

  • Read conditional information from Venn diagrams, tree diagrams or tables and identify the restricted sample space.
  • Calculate a conditional probability as the favourable outcomes within the given condition divided by all outcomes satisfying that condition.
  • Interpret conditional probability in context, including dependent selections and “given that” statements.

CAIE IGCSE Mathematics Extended E8.4.1 Calculate Conditional Probability Using Venn Diagrams Tree Diagrams Questions question 1

[Maximum number: 2]
Dice A

Dice A

Dice B

Dice B

The diagram shows two fair dice.
Dice A is numbered 1,2,2,2,3,6.
Dice B is numbered 2,3,3,4,4,4.

Dice A and Dice B are each rolled once.

Find the probability that when the two numbers they land on have a total of 6 , both numbers are 3.
