Question

An unbiased die is thrown. Which of the following is false. (a) P (odd number) = 1 2 (b) P (even number) = 1 2 (c) P (square number) = 1 3 (d) None of these

Answer 1

Answer:

Let the even A be 'odd' number on the first throw and B the event 'odd number on the second throw'. ... Total no. of outcomes =36 ... As we know that two events A and B are independent if P(A∩B)=P(A).P(B). Now,. P(A).P(B)=21​.21​=41​. ∵P(A∩B)=P(A).P(B). Hence the events A and B are independent.
