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.
Compute.

Nobel Laureates. From Wikipedia and the article "Which Country Has the Best Brains?" from BBC News Magazine, we obtained a frequency distribution of the number of Nobel Prize winners. by country.
Suppose that a recipient of a Nobel Prize is selected at random. Find the probability that the Nobel Laureate is from
(a) Sweden.
(b) either France or Germany.
(c) any country other than the United States.
