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.

What is the probability of drawing a face card or a queen from a 52 card deck?
Since the probability of both events is not mutally exlcusive (you could draw both at the same time), the probability is:
P(queen)+P(face)-P(both)
(4/52)+(12/52)-(4/52)
12/52, which is a bit less than 0.25
What is the probability of drawing a white ball out of a bag with 2 green 3 white and 5 black?
The probability of a simple event is the number of ways to succeed over the total possibilities. So, there are three white balls, and ten balls total. So:
P(white) = 3/10
What is the probability that a coin lands heads up on three consecutive tosses?
For each toss, the probability that it'll land heads up is 1/2
So 1/2 * 1/2 * 1/2 = 1/8, or .125
There is a 12.5% chance that it will land heads-up all 3 times.
What does the probability of a independent event that is likely to happen?
It is a real number between 0.5 and 1. Whether or not it is independent makes no difference to this answer.
How do you draw a Venn diagram to the probability of two independent events a and b?
the circles do not overlap at all.
Are fraternal twins never the same sex?
Fraternal twins can be the same sex or opposite sexes. It doesn't matter.
Assuming without any justification, that X and Y failing are independent events, then the probability that both X and Y fail within a 5-year period is approx 15%.
What does the error code P1130 mean for a Toyota 2000 Sienna LE?
Code P1130 Means air/fuel sensor circuit range/performance (bank 1 sensor 1)
How do you make a dice game with actionscript 3?
Multiple ways:
1. Learn as3, then make a dice game

That's a question better asked in pieces and other places, but ill start you off.
Math.round((Math.random() * (6 - 1)) + 1);
//pseudo-random number between 1 and 6
What is the difference between t-distribution and standard normal distribution?
the t distributions take into account the variability of the sample standard deviations. I think that it is now common to use the t distribution when the population standard deviation is unknown, regardless of the sample size.
What is the probability that you will spin the same number all 3 times but with 8 numbers?
It will be one eighth cubed which is 1/512
