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.

Do some normal probability distributions have different means and different standard deviations?
Yes. Normal (or Gaussian) distribution are parametric distributions and they are defined by two parameters: the mean and the variance (square of standard deviation). Each pair of these parameters gives rise to a different normal distribution. However, they can all be "re-parametrised" to the standard normal distribution using z-transformations. The standard normal distribution has mean 0 and variance 1.

What are the chances of having a boy after having 2 girls?
The male determines the sex of the child and some men are more likely to sire one sex or the other. But, no matter what sex children he's had in the past, his next child is as likely to be a boy or a girl as his first.
What has happened in the past does not affect the odds in the future. That is a man's chances of having a boy after having two girls is the same as it was when he had his first girl. But, because he's had two girls it may suggest he's more likely to sire girls than boys.

Why do complementary events always have a probability of one?
If an event is absolutely certain to happen is then we say the probability of it happening is 1.
Complementary events are such that one of the events musthappen. Therefore the probability of one of a set of complementary events occurring is 1.
For instance : The probability that a fair coin when tossed will come down showing heads is 1/2, and that it will show tails is also 1/2.
The two events are complementary so the probability that the coin toss will result in either a heads or a tails is 1.
Similarly, the probability that a die when rolled will show a number 1, 2, 3, 4, 5 or 6 is 1 as all six events are complementary.
What is the probability of choosing at random a vowel from the word puzzle?
"Puzzle" has 6 letters, and 2 of them are vowels. So the odds of choosing a vowel are 2/6, which equals 1/3, which is one-third or 33.33%.
What is the x-intercept in this linear equation 2y-4x equals -12?
For x-intercept, y = 0
so -4x = -12 therefore x = 3.
A bag has 13 green marbles What is the probability pf drawing out a green marble?
your probability would be 13/13. you would have a 100 percent chance of getting a green marble
The probability that the student will pass is; P(pass)
=
P(10) + P(9) + P(8) =
[10C10 + 10C9 + 10C8] / (.5)10 =
56/1024 ~
~ 0.0547 ~ 5.47%
where nCr =
n!/[r!(n-r)!]
What is the probability of rolling three on a die then rolling a five?
the probability is denoted:
(1/6)x(1/6)=1/36
What is Probability of a gamete getting one of a parents two alleles of a gene?
50% as there are two alleles per gene and four gametes are made from every undeveloped sex cell.
What does the 15 percent tornado probability from the spc typically mean?
A 15 percent tornado probability outook can have a variable meanin due to uncertainty inherent in such forecasts. However, they may often predict moderate tornado outbreaks and sometimes major outbreaks. In such cases strong tornadoes are not uncommon and there is sometimes potential for violent tornadoes. As with other outlooks, some systems are far less severe than anticipated.
