# In a random experiment, a symmetric coin is thrown twice. Find the probability that the eagle will not fall even once.

| Since the coin is thrown twice, then, as in Problem 1, the number of possible elementary outcomes is n = 4. Favorable outcomes of the event A = {the eagle does not fall out once} correspond to option No. 4 of the experiment (see the table in task 1). This option is one, then m = 1.

We find the probability of the event P (A) = m / n = 1/4 = 0.25
