Answer:
998 heads are likely to appear
Step-by-step explanation:
When a fair coin is tossed, the probability to flip a head is 50% and to flip a tail is also 50%, so if the coin is tossed 1996 times, 0.5*1996 = 998 heads and 998 tails are likely to appear, despite the fact the coin lands heads up 4 times before, because every toss is independent of the other ones.
