Question is not clear enough

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
