Coin Toss: Simulation of a coin toss allowing the user to input the number of flips. Toss results can be viewed as a list of individual outcomes, ratios, or table. On a mission to transform learning through computational thinking, Shodor is dedicated to the reform and improvement of mathematics and science education through student enrichmentSuppose you flip a coin ten thousand times. How many heads will you get? On each flip, the coin has equal probability of coming up heads or tails. So, on AVERAGE, you will get five thousand heads and five thousand tails. On the other hand, it doesn't seem likely that you will get EXACTLY five thousand heads -- rather, you will get "about" fiveInstructions. Select 1 flip or 5 flips.The results of the simulated coin flips are added to the Flips column.; Select 1000 flips to add the 1000 coin flips as fast as possible. The cumulative results of the flips are given in the plot showing the cumulative proportion of heads versus the total number of flips.The coin toss is not about probability at all, he says. It is about physics, the coin, and how the "tosser" is actually throwing it. The majority of times, if a coin is heads-up when it is flipped, it will remain heads-up when it lands. Diaconis has even trained himself to flip a coin and make it come up heads 10 out of 10 times.If the coin is fair it should be quite likely to get 560 heads out of 1000. So we calculate that probability as: $\Pr(X=560)=\binom{1000} {560}0.5^{560}(1-.5)^{1000-560}\approx0.00002$. Since the probability of getting 560 heads out 1000 flips if the coin is fair is so very small, I find it very likely to be biased.

So, if you do flip a coin 10 times and see 3 heads, that's a pretty common outcome and you can't conclude that the coin is unfair. What if the same experiment is done by flipping the coin 1000 times? If you flip a coin 1000 times, it's most likely that you'll get heads somewhere between 47 and 53 percent of the times.There are 2^1000 possible outcomes when flipping a coin 1000 times. So this would be the denominator. A subset of these outcomes are all outcomes in which there are exactly 500 heads and 500 tails. The number of such outcomes would be your numerat...If a coin is flipped 1000 times, 600 are heads, would you say it's fair? My first thought was to calculate the p-value. Assume it's fair, the probability of getting 600 or more heads will be .5^1...The 1000 coin flip distribution has a standard deviation of about 16, and results within 3 standard deviations of the mean happen 99.7% of the time. The example you gave (350 heads and 650 tails) is over 9 standard deviations away from the mean, so the probability of a result that skewed is really, really low.

Simulating the probability of head with a fair coin

If we're tossing it 1000 times, then size=1000. Let's keep it simple. We'll toss a coin ten times. So, size=10. The third argument is replace. This takes a boolean value of True or False.Show Work 12. If we flip a coin 1000 times, what is the probability that between 490 and 510 of the flips will be heads? The probability is 4729 13. If we flip a coin 10,000 times, what is the probability that between 4900 and 5100 of the flips will be heads?

If a coin is flipped 1000 times, Six hundred are heads, would you say it is truthful?

My first idea was once to calculate the p-value. Assume it's truthful, the likelihood of getting 600 or more heads shall be

.5^1000 * (c(1000;600) + c(1000; 601) + ... c(1000, 1000))

but then it will be too exhausting to calculate. How to resolve that different ways? Thanks!

You can sure the $p$ price as $$ \sum_i=600^1000\binom 1000i2^-1000\le401\binom 10006002^-1000=1.9\times10^-8 $$ which could be very small. So I wouldn't say it's truthful. There are extra exact techniques however since 0$ up to now off the predicted price, this tough approach is sufficient.

If the coin were fair, then the standard deviation for 00$ flips is 1\over2\sqrt1000\approx16$, so a end result with 0$ heads is kind of $ usual deviations from the imply. If you are conversant in Six Sigma, you'll have grounds for suspecting the coin is not fair.

Just to add to Barry's Cipra answer: Your question follows The Binomial Distribution, hence:

$\mu=np=1\over2*1000=500 $

and $\sigma=\sqrtnp*(1-p)=\sqrt1000*0.5*(1-0.5)=15.8$

Six hundred heads means you are looking at over 6 sigma! So to position it in standpoint, with +Three sigma you might be within the 99.7th percentile. Conclusion: coin is arbitrary.
