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 equation used to determine probability?
Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.
When Rolling 2 dice what is the probability of rolling a number greater then 6?
The probabilities of rolling specific numbers with 2 dice are as follows:
2: 1/36
3: 2/36
4: 3/36
5: 4/36
6: 5/36
7: 6/36
8: 5/36
9: 4/36
10: 3/36
11: 2/36
12: 1/36
Just add up the favorable probabilities in this case.
7/24
How many black honours are present in deck of 52 cards?
There are 26 black cards in a deck of 52 cards.
How do you assign numerical values to indicate the probability of an event?
There are three main methods for assigning probabilities Following the classical definition of probability Using relative frequencies Using subjective probability
What is probability of a drawn card being a club?
The answer depends on how many cards are drawn, whether or not at random, from an ordinary deck of cards, with or without replacement.
The probability for a single card, drawn at random, from a normal deck of playing cards is 1/4.

Pr(3H given >= 2H) = Pr(3H and >= 2H)/Pr(>=2H) = Pr(3H)/Pr(>=2H)
= (1/4)/(11/16) = 4/11.
What are the probable causes of deterioration of efficiency in a machine?
The most probably cause is mechanical wear-and-tear of components. When the machine is doing its work it is exerting forces on the materials that it is working on. By Newton's third law of motion, the material exerts an equal and opposite force on the machine parts. Now, the bit that is being worked on moves on and is replaced by the next bit to be worked on and then the next and so on. But it is usually the same part of the machine that is getting all the reaction. Over time that part wears down and so you get a loss of efficiency.
It depends on a number of different factors. If colorblind is common in either family but the mother/father were lucky enough not to get it, then its a recessive gene. but if its not common in either family then its a very low chance the child will be color blind. Although, if there are numerous people on both sides of the family the probability is very high. It all depends on a lot of different factors. How dominant is the gene? How many relatives are colorblind? If there are any, and they have children, are they colorblind? The easiest way to figure out if the child will be colorblind is to have the kid and test it for colorblind-ness.
What is the probability that you will first roll snake-eyes on the third roll of the dice?
Slightly less than 18 to 1 against.
What are examples of how leadership and management are mutually exclusive?
This is assuming that leadership and management are mutually exclusive. They can very well be the same individual - but here are the distinct ways they COULD be. Management - Ultimately responsible (buck stops here). Management is responsible for each employee's contribution. They are held accountable for such. A Manager could very well be fired for one of his staff's incompetence. Leaders - Do not have the liability of responsibility. Management - Delegates tasks and assignments. Leaders - Motivate others to do more, with no threat of negative consequences. Management - Can use threat of negative consequences as a method of 'motivation' (leadership by fear) that if you don't do something, this will happen...(threats)
What do you mean by exclusive volcanology?
Exclusive volcanology refers to the study and research of volcanoes with a specialized focus. It may involve in-depth investigations into specific volcanic phenomena, advanced analytical techniques, or unique fieldwork methods that contribute to a deeper understanding of volcanic processes and hazards. This specialized approach aims to advance knowledge in the field of volcanology through a concentrated and focused effort.
What is the rejection region and how does it relate to Z score and the p value?
The rejection region for a hypothesis is the set of values such that if the null hypothesis is true, then the probability of observing a value for the test statistic (the z-score) for a random variable that may be assumed to have a Normal distribution, is at least as great as the value actually observed is less than by chance. The latter is an arbitrarily selected value called the p-value - often 5% or 1%.
Note that z-scores may be used only if the random variable is approximately Normally distributed - not otherwise.
5/6 times 5/6 times 5/6 = 125/216
There are 52 cards in the deck.
The probability of drawing the ace of spades on the first draw is 1/52 .
Since you don't put the first card back, there are then 51 cards in the deck.
The probability of drawing the 4 of spades on the second draw is 1/51 .
The probability of both occuring is (1/52) x (1/51) = 1/2,652 = 0.037707 % (rounded)
What is a reasonable degree of medical probability?
The answer depends largely on the probability of coming to an incorrect diagnosis or deciding on a wrong treatment, and the consequence of making that mistake.
