Two coins are tossed once. Consider the following events:
(i) Event E: A tail appears on one coin
Event F: One coin shows a head
(ii) Event E: No tail appears
Event F: No head appears

Which of the following options represents the correct probability of the events E and F?
1) P(E) = 1/2, P(F) = 1/2
2) P(E) = 1/4, P(F) = 1/4
3) P(E) = 1/2, P(F) = 1/4
4) P(E) = 1/4, P(F) = 1/2
