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.

6 to 1. (That is, 6 incorrect to 1 correct.) This is equaivalent to a probability of 1/7 or a 14% chance of guessing the correct answer.
There are 10 possibilities. For every space on the spinner you land on, there are two other outcomes (heads and tails). Say the colors are Blue, Green, Yellow, Red, and Purple. Here would be the final outcomes.
Blue - heads or tails
Green - heads or tails
Yellow - heads or tails
Red - heads or tails
Purple - heads or tails
Where is the deck of cards in where's waldo deep-sea divers?
at the top right, there is a boat sinking, the cards are the bottom of the boat
How many ways can you rearrange the letters in POSSESSES?
9! (nine factorial)
However, since the S is repeated 4 times you need to divide that by 16, and since the E is repeated once, you need to divide that by 2. The final result, which is the number of distinctcombinations of the letters POSSESSES is 11340.
What is the probability that the spinner stops on a multiple of 3?
It depends on the number of numbers on the spinner and what those numbers are.
If you're studying a subject involving or related to statistics and probability, then it will.
If you're not, then it won't.
What is the probability of drawing one joker from a deck of 52 cards?
The question should be ..............from a deck of '54' cards.
P(a joker from 54 cards) = 2/54 = 1/27
What is the sample size for a population of 60010?
well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.
How do you calculate standard deviation on casio fx-991ms?
mode--->SD(select by pressing 1)
Shift mode(CLR) and again 1 to erase any previous statistical Data(SCL)
input the relevent data n press M+ on each interval..then after addin all the data
Shift 2 SD can be taken using either pressing 2(for over 30 data) or 3(for less than 30 data)
What is the probability of drawing either three red cards or three face cards if you choose three?
Red cards will be a 1/3 chance to pick out of three cards .
What is 0.120 kg equal to in grams?
1 Gram = 0.01kg. 1 gram*12 = 12 grams (0.01kg * 12 = 0.12kg (0.120kg)). So 12 grams.

Who are the mathematician behind the probability?
"A gambler's dispute in 1654 led to the creation of a mathematical theory of probability by two famous French mathematicians, Blaise Pascal and Pierre de Fermat. Antoine Gombaud, Chevalier de Méré, a French nobleman with an interest in gaming and gambling questions, called Pascal's attention to an apparent contradiction concerning a popular dice game. The game consisted in throwing a pair of dice 24 times; the problem was to decide whether or not to bet even money on the occurrence of at least one "double six" during the 24 throws. A seemingly well-established gambling rule led de Méré to believe that betting on a double six in 24 throws would be profitable, but his own calculations indicated just the opposite.
The probability of this is based heavily on whether or not said best friend is even in the class. If both are in, it's a 1/870 chance.Ê

Definition for Sum of Absolute Deviations?
The answer depends on absolute deviation from what: the mean, median or some other measure.
Suppose you have n observations, x1, x2, ... xn and you wish to calculate the sum of the absolute deviation of these observations from some fixed number c.
The deviation of x1 from c is (x1 - c).
The absolute deviation of x1 from c is |x1 - c|. This is the non-negative value of (x1 - c). That is,
if (x1 - c) ≤ 0 then |x1 - c| = (x1 - c)
while
if (x1 - c) < 0 then |(x1 - c)| = - (x1 - c).
Then the sum of absolute deviations is the above values, summed over x1, x2, ... xn.
This would increase the mean by 6 points but would not change the standard deviation.
When is a t test better than a z score?
When you don't have the population standard deviation, but do have the sample standard deviation. The Z score will be better to do as long as it is possible to do it.
