there are two possiblities one is H(heads)or the other is T(tails)
S=(HH,HT,TH,TT)
therefore the possiblite depend upon n(s)
Therefore p(a)=n(a)upon(s).

Answer:
No. Actually to say whether it is biased or not, either you should have made the coin or should toss the coin infinite times and then find the probability of head and tail then you can conclude its bias nature. Because for example, if you toss a fair coin or roll a fair die infinite times then in case of coin 1/2 times it will be head and half of the times it will be not and in case of die, 1/6 times a number will occur.
