Question

A toss penny and observe whether it lands heads up or tails up. Suppose the penny is fair, i.e., the probability of heads is 1/2 and the probability of tails is 1/2.This means: every occurrence of a head must be balanced by a tail in one of the next two or three tosses. If a flip the coin many, many times, the proportion of heads will be approximately 1/2 and this proportion will tend to get closer and closer to 1/2 as the number of tosses increases. Regardless of the number of flips, half will be heads and half tails. All the above.

Explanation / Answer

Fair coin means if we flip it again and again many times then the expected number of heads and tails would be equal i.e. the proportion of heads would be approxx 1/2 and this will get closer to 1/2 as we increase the number of flips.

So,

Option B is correct.
