Consider the experiment of rolling a die. Let A be the event 'getting a prime number'. B be the event 'getting an odd number'. Write the sets representing the events (i) A or B (ii) A and B (iii) A but not B (iv) 'not A'.

Explanation

We have, the sample space of an experiment of rolling a die is S = {1,2,3,4,5,6}


Here, A = {2,3,5} and B = {1, 3, 5}


(i) ’A or B’=A ∪ B = {1, 2, 3, 5}


(ii) `’A and B’=A nn B = {3, 5}`
