Determine.
Coin Tossing. When a dime is tossed four times , there are the following 16 possible outcomes.

Here, for example, HTTH represents the outcomes that the first toss is heads, the next two tosses are tails, and the fourth toss is heads. List the outcomes constituting each of the following four events.
A = event exactly two heads are tossed,
B = event the first two tosses are tails,
C = event the first toss is heads,
D = event all four tosses come up the same.
Suppose thatE is an event. Use probability notation to represent
(a) the probability that event E occurs.
(b) the probability that event Eoccurs is 0.436
In Exercises 5.16-5.26, express your probability answers as a decimal rounded to three places.
Russian Presidential Election. According to the Central Election Commission of the Russian Federation, a frequency distribution for the March 4. 2012 Russian presidential election is as follows.

Find the probability that a randomly selected voter voted for
a. Putin.
b. either Zhirinovsky or Mironov.
c. someone other than Putin.
In each of Exercises 5.167-5.172, we have provided the number of trials and success probability for Bernoulli trials. Let X 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) Table VII in Appendix A. Compare your answer here to that in part (a).
