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 rolling a number less that 3 on a number cube?
If it is fair die, then the probability is 1/3.
How many outcomes are there for tossing an odd number on a number cube?
there are three distinct outcomes1,3or5. But there is no probability which will come.
What is the probability of rolling 7 or 11 with 2 dice?
The probability of rolling a 7 on a pair of 2 dices is: P(7) = 6/36.
The probability of rolling a 11 on a pair of 2 dices is: P(11) = 2/36.
The probability of rolling 7 or 11 is the sum of both single probabilities:
P(7 or 11) = 6/36 + 2/36 = 8/36 = 2/9 = 0.2222... ≈ 22.2%.
Explanation.
When rolling a pair of fair dice there are 36 possible equiprobable events or
outcomes. They are:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6),
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6),
(3,1), . . . . . . . . . . . . . . . . . , (3,6),
(4,1), . . . . . . . . . . . . . . . . . , (4,6),
(5,1), . . . . . . . . . . . . . . . . . , (5,6),
(6,1), . . . . . . . . . . . . . . . . . , (6,6).
Each of these 36 events has the probability of happening of 1/36.
For the case of the sum of both dice to be 7, there are 6 possible outcomes, so the
probability of the event sum equals 7 is: P(7) = 6/36 = 1/6.
For the case of the sum of both dice to be 11, there are 2 possible outcomes, (6,5)
and (5,6), so the probability of the event sum equals 11 is: P(11) = 2/36 = 1/18.
How many different outcomes would be possible if you rolled a single die and then two coins?
The single die can land in 6 different ways. For each of those . . .
The first coin can land in 2 different ways. For each of those . . .
The second coin can land in 2 different ways.
Total number of different possible outcomes = (6 x 2 x 2) = 24
IF the coins have different colors so that you can tell them apart.
If you can't tell the coins apart, then there are only 12 different outcomes.
The best known is British Standards Institute, but there are at least 50 other meanings to the abbreviation.
In the year 1964 there was a US Presidential election between the Democratic candidate Lyndon Johnson and the Republican Barry Goldwater, in which Johnson won. This was also a year in which the Beatles gained increasing popularity around the world. There were many other notable events although those are the two that I particularly remember.
What is the probability that a month picked at roandom ends with the later y?
If using the months' names in the English language, it is 1/3.
What are the chances of a female becoming a top executive?
Theorically, women have the same potentiality as men, I would even dare to change 'same' with 'more', since we are usuallymore practical, fast and astute... The reason why there are few top executive women is not to be looked there, but mostly in 'Time Management'. Having such a career requires long hours, days and weeks far from home - and having a family in such circumstances is not only difficult, it's impossible for most of us. How many men would like to stay home taking care of their children and house while their wives are abroad meeting (almost surely) other men? ;) In any case, I know it sounds like a cliché, but really most business men are strongly backed (advised, supported) by their wives - women may not have a highlighted place in the business world, but they are there, working in the backstage.

To work this out, you first need to calculate the probability of the first 8 passing, and the final 2 failing. That is 97%8x3%2 which equals 0.070536902349392649%
The next step is to find out how many different ways the people can be ordered. We have 10 in total and want to order 8, so the number is 10C8, which is 45. Multiply this by the above probability and you get 3.174160605722669205%
Thus the probability that 8 of the next 10 will pass is 3.17%
It is (5/14)^2 = 0.1276, approx.
There are 4 aces, so the odds of drawing an ace are 4/52, or 1/13.
Who introduce complementary events?
It was quite likely to be a prehistoric event since all events are dichotomous: either they happen or they don't happen. Either the sabre tooth will kill me or it won't, either I will find enough prey or I won't. There is no other outcome. So, in each case, the pair of events are mutually complementary.
What is the ratio of choosing a random red card out of a standard deck?
Since there are 26 red cards in all and there are 52 cards in a standard deck, the ratio would be, 26 to 52 or 1 to 2.
What is the probability of getting an eight in a deck of cards?
If you're including jokers, 4/52-if you're not including jokers-4/50 (8%).
Is a standard deviation dependent on the mean?
To find the standard deviation, you must first compute the mean for the data set.
So the answer is yes. Just have a look at the 5 steps needed to compute a standard deviation and you will see why the answer is yes.
In reality, people most often use calculators or computers to do this.
However, it is good to understand what they are doing.
1. Compute the deviation by subtracting the mean from each value.
2. Square each individual deviation.
3. Add up the squared deviations.
4. Divide by one less than the sample size.
5. Take the square root
