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.

If you were to draw a card in a single deck what is the probability of drawing a 2 of spades?

There are 52 cards in a deck and 1 ace of spades. So the probability is 1/52 or unlikely.

You have a 4-card deck containing a queen a jack a 10 and a 9 You draw a random card then put it back and draw a second random card what is probability that you draw a face card?

The chance of NOT drawing a face card both times in a row is 1/4 (a half times a half). That means that the chance of drawing at least one (possibly 2) face cards is 3/4.

What is the probability of getting 2 heads on all 3 tosses?

The probability is 0, since there will be some 3-tosses in which you get 0, 1 or 3 heads. So not all 3-tosses will give 2 heads.

What is the probability of landing the 5 of hearts?

The probability of drawing the Five of Hearts from a standard deck of 52 cards is 1 in 52, or about 0.01923.

What is the sample size definition?

Sample size is the number of samples arawn from a population. If you drew 20 samples, your sample size would be 20.

What is scientific probability?

It is a number expressing the likelihood of the occurrence of a given event, especially a fraction expressing how many times the event will happen in a given number of tests or experiments.

How many ways can you arrange 6 out of 8 books on a shelf?

Ill skip the factorials and just give you what the calculator does in the end.

8*7*6*5*4*3=

Find the probability of getting four consecutive aces when four cards are drawn without replacement from a deck of 52 cards?

The probability of drawing four aces in a draw of four cards from a deck of 52 cards is 3 in 812175. (4 in 52) times (3 in 51) times (2 in 50) times (1 in 49)

What is the probability of rolling a sum of 8 when you toss two number cubes and add?

There are 5 ways to get an 8 (6&2, 5&3, 4&4, 3&5, 2&6) out of 36 outcomes, so the P(8) = 5/36 or 13.89%.

Can airtel sponsor your event?

They presumably can in the sense that they would be able to.

Whether or not they will is a different matter. You should probably contact them directly about this, rather than asking a third party (us).

Deterministic and probabilistic system?

A deterministic system is one that produces predictable set of outputs given a set of specific input parameters. The outputs of a probabilistic system, on the other hand, always vary.

What is the math definition for location?

In math, the definition of a location is a point. A point gives a specific position or location on a plane surface.

How do you roll a good point during a dice game?

There is no way to do that unless you cheat and use loaded dice. The outcome of rolling fair dice is a purely random event and there is no way to control that.

Is there a cargo hole hull or hole in a cargo ship which one is correct?

The term is actually 'cargo hold' and is used for ships and aircraft for holding cargo, typically below decks. Cargo ships, however, generally carry all cargo in huge steel containers above deck and passenger ships' cargo is people, which are appointed cabins throughout the vessel.

What is normal probablity curve?

it is a continuous random variable,mound or bell shaped curve

Can you have a period 4 days after conception?

If you truly conceived, no. Women do not have regular periods after becoming pregnant. What you experienced was probably implantation bleeding. This bleeding is caused by the fertilized egg attaching itself to the uterine wall.

How do you solve for g in a simple pendulum problem?

For a simple pendulum, with very small, technically infinitesimal, swings, the period T is approximately 2 pisquare root (Length / gravity). From there, it is simple algebra.

T2 = 4 pi2 length / gravity

gravity = 4 pi2 length / T2

For more information, including how to compensate for circular error introduced by non-infinitesimal swings, please see the Related Link below.

What is hyper-geometic probability?

The hyper-geometric distribution is a discrete probability distribution which is similar (in some respects) to the binomial distribution. Suppose you have a population of N which contains R successes. The Binomial describes the probability of r successes in n draws out on N with replacement.

However, in many situations the draw is not replaced. In this case you get the hyper-geometric distribution.

The function is given by:

Prob(r successes in n draws out of N) = RCr/[N-RCn-r * NCn]

With the binomial distribution the probability of success remains constant (=R/N) throughout. With the hypergeometric, the numerator for success reduces by one after each successful outcome whereas the denominator reduces by one whatever the outcome.
