I'll assume the question is this:
A fair coin has 2 sides (heads and tails) that are equally likely to show when the coin is flipped. What is P(tails)?
Answer:
P(tails) = 0.5
Step-by-step explanation:
Given:
Number of sides = 2
Number of head = 1
Number of tails = 1
Let P(Tail) = Probability of obtaining a tail when the coin is flipped.
P(Tails) is calculated as follows;
P(Tails) = Number of Tails/Total Number of Sides
Substitute in the values of Number of Tails and Total Number of Sides
P(Tails) = 1/2
P(Tails) = ½
P(Tails) = 0.5
Hence, the probability of obtaining a tail provided that the two sides of the coin are equally likely to show when the coin is flipped is 0.5
