Answer.     [False]
Solution.         Probability: probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

No, because when we toss a coin we can get either tail or head and the probability of each is \frac{1}{2}.
  So, it is not necessary that she gets tail at fourth toss. She can get head also.
