(i) Possible outcomes, if two coins are tossed simultaneously: HH, TT, HT, TH.
∴ n(S) = 4
Out of these possibility of getting 2 heads : 1 ➝ HH
∴ n(A) = 1
Out of these possibility of getting Tail : 1 ➝ TT
∴ n(B) = 1 n(B) = 1
Out of these possibility of getting Head or Tail : 2 ➝ HT, TH
∴ n(C) = 2
∴ This Argument (i) is not correct.
(ii) Outcomes when one die is thrown: 1, 2, 3, 4, 5, 6
∴ n(S) = 6
Out of these, one is odd number ➝ 1, 3, 5
∴ n(E) = 3
Out of these, one is even number ➝ 2, 4, 6
∴ n(E) = 3
∴ This Argument (ii) is correct.
