If E1 and E2 are the mutually exclusive events |
A | i | E1∩E2=E1 |
If E1 and E2 are the mutually exclusive and exhaustive events |
B | ii | (E1−E2)∪(E1∩E2)=E1 |
If E1 and E2 have common outcomes, then |
C | iii | E1∩E2=ϕ,E1∪E2=S |
If E1 and E2 are two events such that E1⊂E2 |
D | iv | E1∩E2=ϕ |
(A) Hint: Use Set theoretic principles
Use the properties of mutually exclusive events
If E1&E2are mutually exclusive events, then E1∩E2=ϕ
(B) Use the properties of mutually exclusive & exhaustive events
If E1&E2 are mutually exclusive and exhaustive events, then
E1∩E3=ϕ & E1∪E2=S
(C) Hint: Use Venn diagram
Use Venn diagram
If E1 & E2 have common outcomes, then (E1−E2) ∪ (E1∩E2)=E1
(D)
Hint: Use Venn diagram
Use Venn diagram
If E1 & E2are two events such that
E1⊂ E2⇒E2=E1
(A)→(iv),(B)→(iii),(C)→(ii),(D)→(i)
