Weighted coins
Here are the various circulating U.S. dollar coin weights: Silver dollars made from 1794 through 1835 — 26.96 grams. Silver dollars made from 1836 through 1839 — 26.73 to 26.96 grams. Silver dollars made between 1840 and 1970 — 26.73 grams. 40% silver dollars made from 1971 through 1976 — 24.59 grams.Yes. (I would have left the answer at that, but the site requires a minimum of 30 characters in an answer. The OP has the right idea in both the "exactly four" and the "less than or equal to four" case.)

To be clear,Some silver coins, which were minted in the United States through 1964, remain in circulation and are often spent as pocket change. But even if sold for scrap or melt price, the silver in the coins far outweighs their face value. Because mo...

A fair coin is an idealized randomizing device with two states (usually named "heads" and "tails") which are equally likely to occur. It is based on the coin flip used widely in sports and other situations where it is required to give two parties the same chance of winning. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: An experiment consists of tossing 4 fair (not weighted) coins, except one of the 4 coins has a head on both sides. Compute the probability of obtaining exactly 1 head. An experiment consists of tossing 4 fair ... Exercise E3 Consider a system of N "weighted" coins, with tails likely to be showing only 40% of the time. (a) Derive a general expression for P (n), the probability of n coins showing heads, as a function of n, N, and p, the probability of tails showing. (b) For N=10 "fair" coins, what value of p should you use? What are the probabilities that ...Other Math. Other Math questions and answers.

If the coin is tossed 8 times, what is the probability of getting less than 3 heads?The answer 0.2889, or more precisely 0.28890625 = (0.6*3/8 + 0.5*5/8)^2, is the result of misinterpreting the problem as selecting a coin, flipping it, putting it back, selecting a coin again, and flipping it. Equivalently, this is the result of mistakenly assuming that the two flips are overall independent.A fair coin is an idealized randomizing device with two states (usually named "heads" and "tails") which are equally likely to occur.

See Answer. Question: An experiment consists of tossing 4 fair (not weighted) coins, except one of the 4 coins has a head on both sides. Compute the probability of obtaining exactly 4 head?To test whether a coin is "reasonably fair" or "weighted" would require relatively few flips before you were pretty confidant which it is. You would require a lot of flips to work out if it is perfectly even or not (e.g. the difference between 49% and 50%), but knowing the difference between a reasonably fair & a weighted coin would be obvious ...Since that special coin has 2 heads, this means we are guaranteed at least one head in the 6 coins. We just need to find the probability of getting exactly 1 head in the five fair coins. We'll use the binomial distribution. n = 5 coins x = 1 head exactly is what we're after p = 0.5 is the probability of getting heads This value is exactThis problem has been solved!

It is the probability distribution of a random variable taking on only two values, 1 1 ("success") and 0 0 ("failure") with complementary probabilities p p and 1-p, 1−p, respectively. The Bernoulli distribution therefore describes events having exactly ... If you want to learn more about the weight of smaller items, you can find items around your house that weigh an ounce. You may be surprised how many common items weigh an ounce. From food items to coins and so many other things, plenty of h...Note that the fact that the coin is fair is not necessary; flipping a weighted coin is still a Bernoulli trial. A binomial experiment might consist of flipping the coin 100 times, with the resulting number of heads being represented by the random variable \(X\). The binomial distribution of this experiment is the probability distribution of \(X.\)
That would mean the coin will have been weighted so that it's more likely to land on one face than the other. So when you toss a fair coin 100 times, you should expect to get roughly 50 Heads and 50 Tails. That is because ... Both coins could land Heads up - that's one result, HH Or both coins could land Tails up ...Question.
