Q. 94.4( 16 Votes )

A die marked 1,2,3 in red and 4,5,6 in green is tossed. Let A be the event that “number is even” and B be the event that “number is marked red”. Find whether the events A and B are independent or not.

Answer :

Let A: number is even

B: number is marked red

For A and B to be independent events, P(AB)=P(A)P(B)

Since here P(AB) ≠P(A)P(B), therefore A and B are not independent events.
