I toss a penny and observe whether it lands heads up or tails up. Suppose the penny is fair, i. e., the probability of
heads is 1/2 and the probability of tails is 1/2. This means

A) if I flip the coin many, many times, the proportion of heads will be approximately 1/2, and this proportion will tend to
get closer and closer to 1/2 as the number of tosses increases.
B) regardless of the number of flips, half will be heads and half tails.
C) every occurrence of a head must be balanced by a tail in one of the next two or three tosses.
D) all of the above.

A) if I flip the coin many, many times, the proportion of heads will be approximately 1/2, and this proportion will tend to

get closer and closer to 1/2 as the number of tosses increases.

Explanation:

Probability is described as the likelihood of an event happening. It is expressed in numerical fractions between zero and one. Zero means near certainty that the event will not occur while one is a guarantee that the event is happening.

A probability of 1/2 signifies a 50 percent chance. In a coin toss, 1/2 probability means the coins have 50 chance of landing on either tail or head. A coin has only two sides. Each ill toss presents a head or tail. The more tosses one makes, the proposition of heads to tail get closer 1/2. Very many tosses will give show 1/2 to either tails or head.
