Probability

It is the process of deciding how large a sample is required so that the variable(s) of interest can be estimated to the desired degree of accuracy.

Since each coin would have the outcome with Heads and Tails:

Then among the 32 coins, we can have the possible outcomes from no Heads, 1 Head, 2 Heads, ....... , 31 Heads, 32 Heads.

Therefore we would have 33 outcomes.

The probability of a boy is approx 51.22%, which is very close to the international mean.

1/2 * 1/6

The answer depends on how many sides the spinners have.

The theoretical probability of HT or TH when two coins are tossed is 1/2 . (All possible outcomes are HH,TT,HT,TH). This means that when we run the experiment repeatedly we expect to get the desired result 1/2 of the time. Since you intend to toss the coins 40 times, 20 are expected.

A z-score of 70 would cover 35 standard deviations away from the mean. Note though, that a z-score of just 2.5 already covers 99% of the data. A z-score of 70 is incredibly high, and so is either a mistake, or will cover 100% of the data without fail. If a data point lies outside this, it is definitely an outlier and probably an error.

The fact that twins run in families is actually a myth. The odds of twins having twins is the same as a non-twin having twins. That is about 1 in 33.

No.

It is partially dependent on how many friends you have. With 6 friends, the chance is over 77% that two of them will have a birthday in the same month.

If you search "birthday problem" you will find many very detailed descriptions of how the formula works.

Be nice, speak politely, keep yourself looking clean and look like your trying to get somewhere in life.

Yes I did! in the early sixties. I remember going to the neighborhood grocery store in So. Cal. and my mother purchasing a pair for 13-15 cents in summertime for all us kids.

Thrice means three times as many. If you have two green balls, it would mean you have six red balls.

What? Pyrrho died more than 18 Centuries before Descartes!

infinitely. I would recommend that you word this question exactly how you read it, so you can get a proper response.

It's over 999 docilion, 999 nonillion, 999 octilion, 999 septillion, 999 sextillion, 999 quintillion, 999 quadrilion, 999 trillion, 999 billion, 999 million, 999 thousand, 999. And that's the biggest number I know.
