An experiment has 10 equally likely outcomes. Let A and B be two non-empty events of the experiment. If A consists of 4 outcomes, the number of outcomes that B must have so that A and B are independent, is

Let A and B be two non-empty subsets of a set X such that A is not a subset of B then

Let A and B be two non empty subsets of set X such that A is not a subset of B ,then:

If A and B are two non-empty sets, then (B-A) nn (A uuB)' is equal to

A coin is tossed twice and all 4 outcomes are equally likely .Let A be the event that first throw results in a head and B be the event that second throw results in a tail , then show that the events A and B are independent .

Let A and B be two non-empty subsets of a set X . If (A-B)uu(B-A)=AuuB , then which one of the following is correct?
