What elements make up nickel coins?

In the U.S. the nickel component of coins is actually an alloy of 75% copper and 25% nickel so "nickels" are actually mostly copper! Dimes, quarters, and halves have a pure copper core with the same 75/25 alloy on the outside layers to give them a silvery appearance. Taken together that means the whole coin is around 85+ % copper. Other countries use different proportions of nickel and copper. For example, Canadian coins from the 1970s to the 1990s were pure nickel, while British 20p coins are about 80% copper.

A bag A conatins 5 dimes and 2 quarters and bag B contains 1 dime and 3 quartersIf a coin is taken from one of the two bags at random what is the probability that the coin is a quarter?

Now the 2 bags contain a total of 6 dimes and 5 quarters, which is a total of 11 coins. Therefore, the probability of getting a quarter is (5/11) which is about 0.4545.... or 45.45% as the case may be. Hope this helps

When was silver taken out of nickels?

The term Silver War Nickels refers to those produced by the United States Mint from mid-1942 to 1945. These nickels differ from those minted before and after World War II, as those were made from 56% copper, 35% Silver and 9% manganese.In WWII, The United States had to use 56% Copper, 35% Silver, and 9% Manganese. The dates for these 35% silver nickels are 1942(P,S) (NOT D), 1943(P,D,S), 1944(P,D,S), and 1945(P,D,S). The mint marks on these coins are located above the dome of Monticello.Contrary to popular misunderstanding, these are the only US nickels that ever contained silver. The rest are all made of an alloy of 25% nickel and 75% copper.

What is the probability density of the wave function?

See related link, In quantum mechanics, a probability amplitude is a complex number whose modulus squared represents a probability or probability density. For example, the values taken by a normalised wave function ψ are amplitudes, since |ψ(x)|2 gives the probability density at position x. Probability amplitudes may also correspond to probabilities of discrete outcomes.

Why do you think is probability used as basis for inferential statistics?

Inferential statistics are used in situations where it can be assumed that random behaviour(s), subject to the mathematical laws of probability, must be taken into account.

yes they can In terms of probability, one is taken to mean absolute certainty, something that must happen, equivalent to a 100% probability (100 out of 100 is equal to one). Hence, odds cannot be greater than one.

Probability of dealing ace king and queen of spades in that order when dealing only 3 cards?

The probability of dealing the Ace of Spades from a normal 52 card deck is 1 in 52. The probability of dealing the King of Spades next is 1 in 51. The probability of dealing the Queen of Spades next is 1 in 50.The probability of drawing those three cards in that order is the product of those probabilities, which is 1 in 132,600. This is the same as the number of permutations of N (52) things taken P (3) at a time, which is stated as N! - P! (52 * 51 * 50)If you did not care what order the cards were dealt in, but still wanted to know the probability of getting the Ace, King, and Queen of Spades, then you would be talking about the combinations of N (52) things taken P (3) at a time, which is stated as (N! - P!) / (N - P)! (52 * 51 * 50 / 3 / 2 / 1). The probability in this case is 1 in 22,100.

Why are guitar strings made of copper and nickel?

Actually, only the lower three strings of guitars contain copper or nickel. These strings are wound, meaning that a core string (usually steel) is taken, and wire (usually nickel or copper) of varying gauge, depending on the thickness of string wanted, is wound around it. The higher three are just steel wire. As for why nickel and copper are used, it's because they are cheap and sound good.
