Q80.Let 𝛺 be the sample space and 𝐴⊆𝛺 be an event. Given below are two statements: (S1): If 𝑃( 𝐴) = 0, then 𝐴= 𝜙 (S2): If 𝑃( 𝐴) = , then 𝐴= 𝛺 Then (1) only (S1) is true (2) only (S2) is true (3) both (S1) and (S2) are true (4) both (S1) and (S2) are false
What This Question Tests
This question tests fundamental definitions in probability theory, specifically the relationship between the probability of an event and whether the event is an empty set (impossible event) or the sample space (sure event).
Concepts Tested
Formulas Used
P(A) = 0 for impossible event
P(A) = 1 for sure event
