Which of the following numbers could not possibly be a probability? Justify your answer.
In each of Exercises 5.167-5.172, we have provided the number of trials and success probability for Bernoulli trials. LetX denote the total number of successes. Determine the required probabilities by using
(a) the binomial probability formula, Formula 5.4 on page 236. Round your probability answers to three decimal places.
(b) TableVII in AppendixA. Compare your answer here to that in part (a).
What does the probability distribution of a discrete random variable tell you?
In Exercises 5.16-5.26, express your probability answers as a decimal rounded to three places.
Coin Tossing. A balanced dime is tossed three times. The possible outcomes can be represented as follows.
Here, for example. HHT means that the first two tosses come up heads and the third tails. Find the probability that
(a) exactly two of the three tosses come up heads.
(b) the last two tosses come up tails.
(c) all three tosses come up the same.
(d) the second toss comes up heads.
Give two examples of Bernoulli trials other than those presented in the text.
