Chapter 11.4, Problem 28E

(a)

To determine

To explain: The outcome of the thumbtack landing point up and the thumbtack landing point down are equally likely.

(b)

To determine

To list: The sample points in the sample space of this experiment.

(c)

To determine

To explain: The probability that both thumbtacks land point up (uu) is the same as the probability that both thumbtacks land point down (dd).

(d)

To determine

To explain: The possibility to compute the theoretical probability of a thumbtack landing point up and the theoretical probability of a thumbtack landing point down.

(e)

To determine

The empirical probability of thumbtack landing point up when dropped and the empirical probability of a thumbtack landing point down when dropped a box of thumbtacks.
