Question

An unbiased die is thrown twice. Let the event A be odd number on the first throw and B the event odd number on the second throw. Check the independence of the events A and B.

Answer 1

P(A)=18/36=1/2
P(B)=18/36=1/2
P(A`nn`B)=9/36=1/4
P(A)*P(B)=1/2*1/2=1/4
so, P(A)*P(B)=P(A`nn`B)
that means they are independent
