Consider the following two binomialexperiments
(a) In a binomialexperiment consisting of six trials, how many outcomes have exactly one success and what are these outcomes?
(b) In a binomialexperiment consisting of 20 trials, how many outcomes have exactly 10 successes?
Based upon past experience, 1% of the telephone bills mailed to households are incorrect. A sample of 20 bills is selected.
a. Is this a valid Binomialexperiment?
b. What is the mean of the probability distribution?
c. What is the standard deviation of the probability distribution?
d. What is the probability that 10 of the
Assume that 12 percent of adults in this country have filed for bankruptcy at some point in their life. If an independent sample of 20 adults is selected find the probability that fewer than 5 will have filed for bankruptcy at some point in their life.
Two marbles are selected, one at a time from a jar of marbles containing 10 black, 10 brown, 10 white and 10 green marbles. Let x represent the number of white marbles selected in 2 separate selections from the jar.
(A) If this experiment is completed without replacing the marbles each time, explain why x is not a binomial

The probability that a house in an urban area will be burglarized is 5%. If 50 houses are randomly selected, what is the probability that one of the houses will be burglarized?
(a) Is this a binomialexperiment? Explain how do you know.
(b) Use the correct formula to find the probability that, out of 50 houses, exactly 4 of
Four cards are selected, one at a time, from a standard deck of 52 cards. Let x represent the number of aces drawn in a set of 4 cards.
If this experiment is completed without replacement, explain why x is not a binomial random variable.
If this experiment is completed with replacement, explain why x is a binomial random
