There is no way to make a sensible estimate without this information.

The key to probability is to identify how many outcomes are possible. Put a bunch of pennies on the table and have your son move them around to indicate how many possibilities there are for arranging two coins. He will quickly find that he can have HH, TT, HT, or TH So tossing two pennies will work out in one of these arrangements -- no matter how many times they're tossed. Probability is a fraction: the number of outcomes that match the criteria [I call these 'winners'] over all possible outcomes. Each of the outcomes in the list, then, has a 1/4 chance of happening. However, 2 of the outcomes result in one head and one tail [the order doesn't matter], so we can group thise to give the 1head-1tail choice a total probability of 1/2 Once you have the basic fraction of probability, he can multiply that by the number of tosses to work out the specific answers for your questions above
There are 100 Pennies in a Dollar. >> and 5 Pennies in a Nickel. >> and 10 Pennies in a Dime. >> and 25 Pennies in a Quarter. >> and 50 Pennies in a Half Dollar.
$900 = 90,000 pennies

It is incalculable.
You can use a metal polish to get pennies back to looking new.
Well, isn't that a happy little problem to solve! If there are five coins with a total value of 27 cents, and we want three of them to be pennies, that means the other two coins must add up to 6 cents. The probability of randomly selecting three pennies out of five coins is like painting a beautiful landscape - it's all about understanding the colors and creating a harmonious composition. So, the probability would be the number of ways to choose 3 pennies out of 5 divided by the total number of ways to choose 5 coins. Happy calculating!
Of course. If there are seven pennies and thirteen dimes in a bowl, and you pick up one coin with your eyes closed, the probability of picking up a penny is 35%.
If you are looking to sell wheat pennies you can sell them on eBay or take them to a local coin shop. If you have friends or relatives that would like to buy them you could sell them to them.
