In a random experiment, a symmetric coin is thrown three times. Find the likelihood that the second throw has tails

What are the possible outcomes of three coin tosses?
1) Tails, tails, tails.
2) Tails, tails, heads.
3) Tails, heads, tails.
4) Eagle, tails, tails.
5) Tails, eagle, eagle.
6) Eagle, tails, eagle.
7) Eagle, eagle, tails.
8) Eagle, eagle, eagle.
These are all possible events, there are no others. We are interested in the probability of the 1st, 2nd, 4th, 6th event.
Total possible outcomes 8.
Favorable outcomes – 4.
4/8 ratio = 0.5
