Q
What are mutually exclusive events ?
A
Events which can’t happen at the same time ( so the Venn diagram can’t overlap)
2
Q
What is P(A n B) if A and B are mutually exclusive?
A
P(A n B) = 0
3
Q
What is P(A u B) if A and B are mutually exclusive?
A
P(A u B) = P(A) + P(B)
4
Q
What are independent events ?
A
When 1 event happens it doesn’t affect the probability of the other one happening
5
Q
What is P(A n B) if A and B are independent events ?
A
P(A n B) = P(A) x P(B)
6
Q
Does independent events affect how the circles in the venn diagram interact ?
A
NO - Independent events don’t affect how the circles interact in a Venn Diagram
