1/4 you see if you flip two coins there's a better chance you'll get a head and a tail then any thing else. 2/4 you'll get a head and a tail, 1/4 you'll get two heads and 1/4 you'll get two tails.
Since the probability is 1/4, the number of times this will happen will likely be close to 68 divided by 4.
A fair coin would be expected to land on heads 10 times on average.
50%
you would think there is a 50% chnce of it landing on heads. However due to the weight of the metal on the picture on the coin it is actually about 5009/10,000 chance it will land on heads.
Assuming the penny is unflawed, yes it should. The more times you flip it, the closer the split should be to 50/50.
When flipping two coins, the probability of both landing on heads in a single flip is ( \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} ) or 25%. If you flip the coins 20 times, the expected number of times both will land on heads is ( 20 \times \frac{1}{4} = 5 ). Thus, while the odds for any single flip remain at 25%, over 20 flips, you would expect about 5 occurrences of both coins landing on heads.

There is a 1/8 chance to land three heads.
The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.
Luck of the flip, but they do not always land heads up.
When flipping two coins, each coin has two possible outcomes: heads (H) or tails (T). The total number of outcomes when flipping two coins is 2 × 2 = 4, which includes HH, HT, TH, and TT. Out of these four outcomes, only one results in both coins landing on tails (TT). Therefore, the probability of both coins landing on tails is 1 out of 4, or 25%.
Since the probability is 1/4, the number of times this will happen will likely be close to 68 divided by 4.
The probability that exactly one will land heads up is 0.15625
A fair coin would be expected to land on heads 10 times on average.
When flipping four fair coins, the number of ways to get exactly three heads can be calculated using combinations. Specifically, there are ( \binom{4}{3} = 4 ) ways to choose which three coins will land on heads. The probability of any specific combination of three heads and one tail is ( \left(\frac{1}{2}\right)^4 = \frac{1}{16} ). Therefore, the total probability of getting exactly three heads is ( 4 \times \frac{1}{16} = \frac{4}{16} = \frac{1}{4} ) or 25%.

No there is a fifty fifty chance of getting heads or tails
