A person having three coins, first coin have both sides head, second coin
and third coin having one head and one tail. If one coin is picked up randomly
and tossed then the probability that it shows head having tail is...

• p(selecting any coin)=1/3
  p(h)=p(t)=1/2
  p(getting head from coin with tail)=p(selecting one of the coin(with tail))xp(h)
  =1/2*1/3+1/2*1/3
  
  =1/3 ans

• 3c2/3c3
  =3

• probability to getin tail in two opposite sided coin =probability to getin tail from 2 coins/probability to getin oppo side coin from two
  
  
  
  so
  p(t)=(2/4)/(2/3)=3/4 ans
