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 Probability of drawing a spade or ace from 52 card deck?
The probability of drawing a spade or an ace from a 52 card deck of standard playing cards is 16 / 52 or approximately 30.8%.
There are 13 spades in a standard deck of cards.
There are four aces in a standard deck of cards.
One of the aces is a spade.
So, 13 + 4 - 1 = 16 spades or aces to choose from.
Since we have a total of 52 cards, the probability of selecting an ace or a spade is 16 / 52 or approximately 30.8%.
What is the probability of drawing a red queen in a pack of playing cards?
The probability of drawing a red queen in a complete package of playing cards (ignoring jokers) is 1/26 or approximately 3.8%.
There are 26 red cards in a deck of 52 cards. There are 2 red queens in those 26 red cards (one queen of diamonds and one queen of hearts). SO:
2 / 52 = 1 / 26 = approximately 3.8%.
What is diffenrence between balance of probabilities and beyond reasonable doubt?
The balance of probabilities is the standard used in civil cases, and can be made to fit any situation in order to find in favour of one side rather than the other. They do not have to have any proof that what they believe to be the case is the case. They can ignore all evidence to the contrary even when "on the balance of probabilities" the opposite of what they believe to be the case is supported by hard factual evidence! Unfortunately this is used in civil cases that can have serious ramifications for someone's employment and financial retribution.
Beyond reasonable doubt is the standard used in criminal cases, where there is strong evidence to suggest that what the accused has been charged with is most likely to be the case! It is used in criminal cases as there is a chance that if convicted a person may serve a custodial sentence and will have any sentence passed disclosed when applying to work with children or vulnerable adults.
Beyond doubt is not just someone's opinion but is based on sound evidence and looks at all evidence available rather than disgarding evidence that does not fit with the case. This can happen often in "balance of probability" cases. I strongly believe that beyond reasonable doubt should be used for both civil and criminal matters!
What is the probability of drawing a 4 or a club in a deck of cards?
In a standard 52 card deck, there are 13 clubs and 4 4s. However, the four of clubs is in both lists, so this represents only 16 distinct cards (the 13 clubs, and the 3 other 4s).
The probability of drawing one of these 16 cards is 16/52, or 4/13.
What is the possibility of two heterozygous parents having identical twins?
Heterozygous parents have the same odds of identical twins as the general population.
Identical twins do not run in families and, therefore, twinning is not related to genetics. Comparisons among different ethnic groups rule out an ethnic cause-no difference.
Only mother's age correlates with twinning: the older the mother, the greater the likelihood.
1/2. or 50%. You can draw a red card, or you can draw a black card.
However, if you have already drawn 10 black cards and 0 red cards then the probability of drawing a black is:
16(remaning black cards)/42(remaning cards)
=38%
What is a sub main distribution board?
A sub main is a distribution board fed from the main distribution board panel normally protected via a CPD.
What is the probability of being dealt the queen of hearts from a deck of cards?
1/52
there is only one queen of hearts in the deck and there are 52 cards in a deck (not counting jokers).
If a population consists of 54000000 people and a census is taken how many people are sampled?
A census would require data to be collected from 54000000 people.
What type of probability is determined by personal experimentation and testing?
Empirical probability.
What is the probability of not being dealt a queen from a deck of 52 cards?
The answer depends on how many cards are dealt out to you - which depends on how many cards you are dealt.
What does the ace of spades with wing biker tattoo mean?

What is the probability of getting killed in a car crash?
There is not enough information to give a sensible answer to the question.
I am in a room on the first floor of a building. The probability of my getting killed in a car crash in the next ten seconds is pretty close to zero. . . . . . . . . . . Yes, it was zero.
If I was trying to drive across town at top speed, while wearing a blindfold, I would say that the probability is quite high.
The probability depends on:
- your location,
- your activity,
- the time span for the event,
- your vehicle - and its safety,
- the presence of obstacles or other vehicles,
- your speed, and those of other cars in the vicinity,
- your driving skills and the skills of other drivers,
- your desire to remain alive.
You have not provided any information on these factors and so it is not possible to give a more helpful answer.
A coin is flipped 3 times. What is the probability of getting 3 tails in a row?
A random sample of size 36 is taken from a normal population with a known variance If the mean of the sample is 42.6. Find the left confidence limit for the population mean.
