The document describes a probability experiment of drawing 5 cards from a standard deck without replacement and noting whether each card is a diamond or not. The probabilities of drawing a diamond (success) on each trial is 1/4, while the probability of drawing a non-diamond (failure) is 3/4. A binomial distribution with n=5 trials, probability of success p=1/4 and probability of failure q=3/4 is presented.
