If `n(A) = 6` and `n(B) = 8` and `n(A nn B) = 4`, then find `n(A Delta B)`.
The following are the step involved in solving the above problem . Arrange them in sequnential order.
(a) `n (A uu B) = n(A) + n(B) - n(A nn B)`
(b) `n(A uu B) = 10`
(c )`n(A uu B) =6+8-4`
(d) `n(A Delta B) = 10-4= 6`
(e) `n(A Delta B) = n(A uu B) - n(A nn B)`.
