Coin flipping, coin tossing, or heads or tails is the practice of throwing a coin in the air and checking which side is showing when it lands, in order to randomly choose between two alternatives. It is a form of sortition which inherently has two possible outcomes.
The symbols H and T represent more generalised variables expressing the numbers of heads and tails respectively that might have been observed in the experiment. Thus N = H + T = h + t. Next, let r be the actual probability of obtaining heads in a single toss of the coin. This is the property of the coin which is being investigated.
Player A selects a sequence of heads and tails (of length 3 or larger), and shows this sequence to player B. Player B then selects another sequence of heads and tails of the same length. Subsequently, a fair coin is tossed until either player A's or player B's sequence appears as a consecutive subsequence of the coin toss outcomes. The player ...
Using for heads and for tails, the sample space of a coin is defined as: = {,} The event space for a coin includes all sets of outcomes from the sample space which can be assigned a probability, which is the full power set. Thus, the event space is defined as:
If after tossing four heads in a row, the next coin toss also came up heads, it would complete a run of five successive heads. Since the probability of a run of five successive heads is 1 / 32 (one in thirty-two), a person might believe that the next flip would be more likely to come up tails rather than heads again. This is incorrect ...
In some games, coins are placed tails (white cross) up. In casino games the coins are placed with opposing (one head, one tail) sides up. Toss the Kip The Spinner hands the kip back to the Ringkeeper before a possibly losing throw, i.e. to retire after a winning throw. Heads Both coins land with the "head" side facing up.
Feller's coin-tossing constants are a set of numerical constants which describe asymptotic probabilities that in n independent tosses of a fair coin, no run of k consecutive heads (or, equally, tails) appears. William Feller showed [1] that if this probability is written as p(n,k) then
"flip a coin" will flip a coin: heads or tails. [95] [23] "fun facts" or "i'm feeling curious" will show a fun fact. Once a search result has been given, clicking on "Ask another question" will show another question.
