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 probability of getting an even number and a head when rolling a die and then tossing a coin?

These are unrelated events, so simply multiply them. 3 in 6, or 0.5 for the die, and 1 in 2, or 0.5 for the coin, multiplied together gives you 0.25.

The change that a given event will occur usually expressed between the number 0 will not and 1 the event will occur?

The chance that a given event will occur that is usually expressed between the numbers 0 and 1 is known as probability.

What is the probability if you want to move ahead 4 spaces on the board?

Suppose the moves are based on throws of a regular die. A move ahead of 4 spaces can be achieved by for moves of 1 each, two of 1 and one of 2, one of 1 and one of 3, two of 2 or one of 4. So the probability of these outcomes is

(1/6)4 + 3*(1/6)3 + 2*(1/6)2 + (1/6)2 + (1/6) = 0.2647 approx.

How many color card and 10s in a deck?

Assuming that colour cards refer to what most people would call picture cards, the answer is 16.

How do you compute the probability pY and gtu given a random variable Y has a normal distribution with mean m and variance s2.?

You find z = (u - m)/s and the look up the Pr(Z > z) in the tables of cumulative probability of the normal distribution. Note that the tables only give the probabilities for Pr(Z <= z) for z >=0. So Pr(Z > z) = 1 - Pr(Z<=z). Also, if z < 0 then you will need to use the symmetry of Z about the value 0.

What is probability of getting 20 multiple choice questions wrong in a row?

Let us say that for each question, there are n multiple choices. If this is true and false, then n=2. The chance of getting a right answer is 1/n and wrong answer (n-1)/n. I will define p as getting a wrong answer one time (p = (n-1)/n so the probability of 20 wrong answers is p20. Now for n = 4, p=0.75 and the chance of 20 wrong answers in a row is: (0.75)20= 0.0032 or 0.32%.

How do you get relative frequency?

The relative frequency of an event, from repeated trials, is the number of times the event occurs as a proportion of the total number of trials - provided that the trials are independent.

What is the difference between sample and sample size?

a sample is a sample sized piece given... a sample size is the amount given in one sample

What is the probability of drawing a heart in a deck of cards?

The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty.

The probability on a single random draw is 1/4.

A five appears in a throw of a fair die?

if the dice is fair any side has the same chance to appear, 6 sides, so each side has a probability of 1/6 to appear

Twins that come from the same egg and sperm?

Yes, during the process, I believe the Zygote -pretty much randomly- divides into two, which leads to genetically equivalent twins (whether or not they are identical is another story).

Why are identical twins and fraternal twins not the exact same?

Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.

What is the probability of seeing a rainbow tomorrow?

The answer will depend on where you are, and the local weather forecast.

How do you change over to HEI distributor from points?

It's a fairly simple procedure. The biggest thing you have to do is run a 10-12 gauge wire to the hot side of the coil in the distributor. The original small wire to your coil isn't heavy enough. Just make sure to wire to something that is hot only when the key is turned on. Other than that, run the vacuum advance of the HEI to a ported vacuum....not the manifold vacuum that the point style uses. Basically any vacuum port on the carb that is above the base plate.
