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.

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.
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.

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
Pr(3H given >= 2H) = Pr(3H and >= 2H)/Pr(>=2H) = Pr(3H)/Pr(>=2H)
= (1/4)/(11/16) = 4/11.

How many black honours are present in deck of 52 cards?
There are 26 black cards in a deck of 52 cards.
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 probability of winning the lottery on 1 ticket by picking 5 numbers out of numbers 1-50?
The number of combinations of 50 things taken 5 at a time is (50! - 45!) / 5! or 2,118,760, so the probability of winning the lottery on 1 ticket by picking 5 numbers out of 50 numbers is 1 in 2,118,760, or 0.00000047197.
More formally, the number of combinations of N things taken P at a time is (N! - (N-P)!) / P!
How do you make a diagram showing electricity coming from copper coins?
This website does not have the ability to draw and show the diagram.
Can colorblindness be passed on through genes?
yes, although not all the persons who have the color blindness 'genes' actually suffer its effects. they can be just carriers, who pass on the genes to the next generation.
fyi: mostly males are affected by color blindness
How do you play level 16 rotate and roll on coolmath4kidscom?
Keep rotating back and forth but first escape the spike monster in the middle my by moving left or right, right as you start to fall eventually.The ball will get confused and rotate in the opposite direction and it will go to the top and fall on the bubble trust me its not as easy as you think.
