Mr. Jackson likes to play a game in which rolling a 4 on a number cube doubles your score. He wants to know the probability that he will roll a 4 exactly 3 times out of 10 rolls.
Define the variables for describing a binomial probability, and identify their values in this experiment.
a. P = the probability of (rolling a 4) =
b. Q = probability of (rolling anything other than a 4) =
n = number of (the number of times the number cube is rolled) =
x = number of you want =
