Document Summary
Probabilities using the probability mass h - n function to create a table of values. Distribution single trials in binomial experiments out no comes with trials for. Example 1: the following experiment is designed to determine if a subject has esp (extra sensory perception). The subject is told that on the backs of a deck of cards one of three gures has been drawn, a triangle (t), a square (s) or a circle (c). The experimenter chooses a card at random, pictures the drawing on the card in his mind, and asks the subject to "read his mind" and correctly identify the drawing on the card. If the subject is guessing (i. e. picking t, s or c at random) nd the probability that she gets (a) exactly 3 correct, (b) three or fewer correct. X = number of correct guesses out of 5 . X is binomial: p(x=n) =p (a, pl.
