What is the best prediction possible for the number of times it will land on tails?

The greatest number of times both coins will land on tails is 4 but again it is relatively unlikely with a chance of 1/256.

What is the probability that the coin will land on tails?

Suppose you have a fair coin: this means it has a 50\% chance of landing heads up and a 50\% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up?

How often does a coin land on tails?

According to Diaconis’ research, a spinning penny will land tails side up roughly 80 per cent of the time. This is because the heads side of the penny, the one with the portrait of Abraham Lincoln on it, is slightly heavier than the tail side.

When tossing two fair coins four times what is the probability that both land on heads at least once?

0.25
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

How often does a coin land on its edge?

However, even on a flat surface it is possible for a coin to land on its edge. A computational model suggests that the chance of a coin landing on its edge and staying there is about 1 in 6000 for an American nickel.

What is the probability of tossing a coin 4 times?

1/16
1) Consider the experiment of flipping of 4 coins. If we assume that each individual coin is equally likely to come up heads or tails, then each of the above 16 outcomes to 4 flips is equally likely. Each occurs a fraction one out of 16 times, or each has a probability of 1/16.

How often does a coin land on a tail?

Assuming the coin is a “fair” coin, the most frequent result should be that the coin lands on tails 50\% of the samples, so 35 tails.

What is the probability of flipping a coin and getting heads?

If the coin is fair and it is flipped correctly, then all outcomes (1 to 80 times head or tails) are possible but with different probabilities. The event with highest probability (0.0889278) is 40 heads and 40 tails.

What is the expected value of a tail on a graph?

In other words, if you repeat this experiment a large number of times, you can expect to obtain between 27 and 43 tails 95\% of the time. The “best prediction” is called the expected value, and it is 35. However, getting exactly 35 is not very likely (it’s just more likely than any other answer).

What is the probability of getting 35 tails?

While 35 tails is the more likely than any other single outcome, in other words 35 tails is more likely than 34 or 36 tails which in turn are more likely than 33 or 37 tails which are in turn more likely than 32 or 38 tails and so on. But the probability of getting exactly 35 tails is only 9.5\%.
