P(X = x) 0.22 0.69 0.09
Reason
A) Since the probabilities lie inclusively between 0 and 1 and the sum
of the probabilities is equal to 1.
Decide
B) Since at least one of the probability values is greater than 1 or less
A) Yes
than 0.
B) No
C) Since the sum of the probabilities is not equal to 1.
D) Since the sum of the probabilities is equal to 1.
E) Since the probabilities lie inclusively between 0 and 1.
Assume the random variable X has a binomial distribution with the given proba'
obtaining a success. Find the following probability, given the number of trials a
probability of obtaining a success. Round your answer to four decimal places.
