What happens if you flip a coin 100 times?
It’s unlikely that you will come across a coin that is biased. So when you toss a fair coin 100 times, you should expect to get roughly 50 Heads and 50 Tails. That is because Heads and Tails are equally likely. The probabilities of each event – Heads and Tails – are both equal.
When tossing a coin twice what is the sum of all possible outcomes?
Repeated probability experiments: When you toss a coin there are two possible outcomes: ‘heads’ or ‘tails’. Each of these outcomes is equally likely, since there is 1 ‘head’ and 1 ‘tail’ on the coin. If a coin is tossed twice, what is the probability of ‘heads’ coming up both times?

When 100 coins are tossed what is the probability that exactly 50 are heads?
It is assumed that a fair coin is being tossed, i.e., getting a head and getting a tail have equal probability of 0.5. If you toss the coin 100 times, number of possible outcomes = (2^100). Now, for getting 50 heads in 100 tosses, number of possible outcomes = (100C50). So, the probability = (100C50) / (2^100).
Is flipping a coin always 50 50?
For example, even the 50/50 coin toss really isn’t 50/50 — it’s closer to 51/49, biased toward whatever side was up when the coin was thrown into the air. The spinning coin tends to fall toward the heavier side more often, leading to a pronounced number of extra “tails” results when it finally comes to rest.
