Probability based on discrete distribution.

As the number of tosses of a fair coin goes up from 10, to 100, to 1,000 and to 10,000, what happens to the probability of getting between 40% and 60% heads? What happens to the probability of getting exactly 50% heads?

A)     Both of those probabilities increase.

B)     Both of those probabilities decrease.

C)     The first probability increases, but the second one decreases.

D)     The first probability decreases, but the second one increases.

E)      We don’t know until we toss the coin.

You read in a book about bridge that the probability that each of the four players is dealt exactly one ace is about 0.11. This means that

A)     in every 100 bridge deals, each player has one ace exactly 11 times.

B)     in one million bridge deals, the number of deals on which each player has one ace will scarcely be within ± 100 of 110,000.

C)     in a very large number of bridge deals, the percent of deals on which each player has one ace will be very close to 11%.

D)     in a very large number of bridge deals, the average number of aces in a hand will be very close to 0.11.
