Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

How does probability distribution looks like when tossing a coin 3 times?
Pr(3 Heads) = 0.125
Pr(2 Heads and 1 Tail) = 0.375
Pr(1 Head and 2 Tails) = 0.375
Pr(3 Tails) = 0.125
What is the probability of getting three boys out of three children?
I wouldn't say it's very probable. My neighbor has three children and they're all boys. It just depends on the mother and father.
British slang for an "idiot", a contemptible person. Also, occasionally spelled "tossa".
I believe it is a politer form of "wanker," Am. Equiv. would be "a jerkoff."
Before the advent of waterborne sewage systems waste buckets were left on the corners of streets for collection. People used to toss the waste in the buckets sifting through it for valuable items: rings; watches; and broaches, very much like down-and-outers rummage through rubbish (garbage) bins in affluent areas today. The sheer ghastliness of shifting through human excrement meant that the term 'tosser' conjured up depravity and poverty, and it was a very bad insult indeed.

Flabbergasted means "astounded, thunderstruck, astonished, struck dumb."
In other words, it means to be overcame with surprise and bewilderment, to be overwhelmed with shock or wonder, to be astonished, to be stroked with wonder (especially by extraordinary statements), or to shock someone (usually by telling them something they were not expecting).
Used in an example sentence: "He was flabbergasted when we told him how cheap it was."
Surprised, astonished and flabbergasted all mean shocked and amazed.
Well... a spinner is used for entertainment. When you
make it, youfold the creases, then spin it. A spinner is
used, as I said before, for entertainment.
Zero - all five digit numbers are higher than 4000.
There are two types of twin, monozygotic (identical) or dizygotic (fraternal, non-identical) and each type is created in a different way explained below:
1) Monozygotic Twins. These type of twins both com from the same fertilized (zygote) and so have exactly the same genetic make up and will look exaclty like one another. Once the zygote has developed up to a certain point it splits into two, separate zygotes. This is often because the mother has received a mild bump, not enough to be fatal, to the stomach. These two new zygotes will go on to grow and develope as normal although they may well be stunted in size because of the lack of space to grow and because they share the same placenta and to have to compete for nutrition.
2)Dizygotic Twins. These type of twins com from two separate eggs and so are only as similar as any two brother/sister compination. This type of twin occurs when both of the mothers overied are active at the same time and both produce and ovum. The fathers sperm is easily enough to fertalize the two eggs both of which will then implant into the uterus and develope into babies. These type of twins, unlike the ones above, each have their own placentas so the only reason for them to be stunted in size is the lak of space.
No, the Pearson coefficient does not equal 40.
2/5 x 1/4 x 5/8 x 3200 = 200 of the people.
Do units of measure follow the standard deviation?
Units of measure do follow the standard deviation.
What is the probability with 15 red pencils and 10 blue pencils of picking 1 red one?
60% chance or 15/25
1317 to 1705
1511+194= 1705
1511-194=1317
What is the probability of getting a number under five?
There is insufficient information in the question to properly answer it. "Getting a number under five doing what?" rolling dice? turning a spinner? drawing a card? Please restate the question.
What is systemic random sampling?
In order to do a systemic random sample, the items or individuals in the population are arranged in a certain way (for example, alphabetically). A random starting point is selected and then every __th (for example: 10th or 15th) individual is selected for the sample.
In a standard deck of cards it is one with a value ranging from 2 to 10 (inclusive).
Well it would really depend on how many sections there are in the spinner and how many 3's and 5's there are.
