How many outcomes if you flip 3 coins?
-- 8 possibilities if the coins are different colors. -- Only 4 possibilities if you can't tell the coins apart.
How could you arrange 6 coins so that you have 3 coins with 3 coins in each row?
Form a triangle with the six coins. Now you have 3 rows with 3 coins in each row!
If you flip 3 coins what are the odds that they all land same side up?
Ok, I'm admittedly not a probability geek, but here is my reasoning... if you flip two coins there are only two possibilities... alike or different, and that's 1 in 2 or 50/50 odds. When you add the third coin it's automatically going to match at least one of the other two... unless the other two were alike and it falls differently. so it does decrease the probability of all matching, and there are three opportunities for one of the coins to be different. So I say it's 1 in 3.
If you have 43 cents and 8 coins what are the coins and the number of coins?
3 dimes, 2 nickels, and 3 pennies
Can you make 26 cents with 3 coins?
No, you cannot make 26cents with 3 USA coins. with 2 coins - 1 quarter and 1 penny with 4 coins - 2 dimes, 1 nickel and 1 penny with 5 coins - 1 dime, 3 nickels and 1 penny with 6 coins - 5 nickels and 1 penny etc
