because it is easy to say and it sounds better than heads or eagles.
Please use the Advanced Search feature on this site to look for postings with "double" in their titles. This question is asked frequently and the answer is the same in each case: There are no genuine modern coins with two heads or two tails. It's a fake.
hard to say...but being that old, it could be worth a lot to somebody who collects coins hard to say...but being that old, it could be worth a lot to somebody who collects coins
You have to explain what type of coin it is. Is it a British Sovereign? Canadian Maple Leaf? Australian Nugget? Etc. There are many modern bullion coins that feature Queen Elizabeth II on the obverse ("heads") but for modern bullion coins it is usually worth simply the precious metal content of them. On most bullion coins other than the British Sovereign it will say something like "One troy ounce pure gold" or "one half troy ounce pure gold" then you find out the spot price of gold and figure out how much gold is in your coin and figure it out from there.
I would say yes. When has paper money ever held it's value?
Yes coins will be manufactured as demand. A best challenge coin maker can handle this easily. There are multiple coins for sale.
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.
There are eight possible results when flipping three coins (eliminating the highly unlikely scenario of one or more coins landing on their edge): Dime - Heads / Nickel - Heads / Penny - Heads Dime - Heads / Nickel - Heads / Penny - Tails Dime - Heads / Nickel - Tails / Penny - Heads Dime - Heads / Nickel - Tails / Penny - Tails Dime - Tails / Nickel - Heads / Penny - Heads Dime - Tails / Nickel - Heads / Penny - Tails Dime - Tails / Nickel - Tails / Penny - Heads Dime - Tails / Nickel - Tails / Penny - Tails
Because you are thinking permutations rather than combinations. There are four permutations of two coins, but there are only three combinations, because it does not matter which coin is heads and which coin is tails. As a result, the combination of heads and tails has a 0.5 probability, while two heads or two tails each have a 0.25 probability.
Four coins.
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
No there is a fifty fifty chance of getting heads or tails
Heads and HeadsHeads and Tails Tails and HeadsTails and Tails
Two ways to think about it: 1: 25% both heads 50% one of each 25% both tails -or- 2: 25% heads/heads 25% heads/tails 25% tails/heads 25% tails/tails
three heads two head, one tails one heads, two tails three tails
10 coins would be tails up.
Assuming the coins are fair, two-sided coins, and landing on their sides is not an option, there are four possible outcomes if you consider coin a having a head and coin b having a tail being a different instance from coin a being a tail and coin be having a head. Here they are; Coin A | Coin B Heads | Tails Heads | Heads Tails....| Heads Tails....| Tails
fifty cats or fifty coins...
