One typical problem that follows the geometric distribution is to determine the number of times a flipped coin comes up tails before it first comes up heads. This distribution can be used to describe many interesting situations, from the probability of observing a particular sequence of coin flips, to the distribution of darts hitting a dart board, to the probability of observing particular speeds of atoms and molecules. We are conducting an experiment in which we are flipping a fair coin 5 times and counting how many times we flip heads

Whether or not the coin lands on heads is a categorical variable with a probability of 0.50.
We explain how to calculate coin flip probabilities for single and mutiple flips
We provide many examples to clarify these concepts. I'm assuming you are asking what is the probability (p) of flipping a quarter This answer really depends upon how many times up are going to flip it If you are flipping it once, you have.
When you flip a fair coin, the two possible outcomes, heads (h h) or tails (t t), have equal probability If an experiment consisted flipping one coin and recording the number of heads observed, we could let the random variable n n be the observed number of heads. The probability that a quarter will land tails up each time when flipped 4 times is 0.0625, or 6.25% This is calculated by multiplying the probability of getting tails for each individual flip since each flip is independent.
