An example of binomial probability equations is a set number of trials (n) each trial can be classified as a "success" or "failure" the probability of success (p) is the same for each trial results from each trial are independent from each other Steph makes of the free-throws she attempts. She is going to shoot free-throws. Assume that the results of free-throws are independent from each other. She wants to find the probability that she makes exactly of the free-throws. N=3 each free-throw is a "make" (success) or a "miss" (failure) probability she makes a free-throw is P=0.90 assume free-throws are independent P(makes 2 of 3free throws )=3C2*(0.90)2*(0.10)1 =3*0.81*0.10 =3*0.081 =0.243
