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.

How many numbers on a standard six sided dice?

Six, one for each side. 1, 2, 3, 4, 5, and 6.

What is the probability that you draw a 9?

...from what? Is is essential to know the properties of the items you are drawing from.

If the question applies to a deck of cards (which the wording alludes to), then the probability is 1/13.

There are 4 9's in a deck of cards, and there are 52 total cards. 4/52=1/13

Why is the normal probability distribution called a family of normal probability distribution?

Because very many variables tend to have the Gaussian distribution. Furthermore, even if the underlying distribution is non-Gaussian, the distribution of the means of repeated samples will be Gaussian. As a result, the Gaussian distributions are also referred to as Normal.

What is a tree diagram?

We make a tree diagram if there are multiple ways to combine different things. For example, you could have two kinds of bread, three kinds of meat, and two kinds of cheese for a sandwich choice. A tree diagram lets you organize all of the possibilities and makes them easy to count and list. I can only use horizontal lines, but I'll try to show you.

white bread--ham--cheddar

--swiss

-- turkey--cheddar

--swiss

-- salami--cheddar

--swiss

The tree would look the same for wheat bread. So for white bread, there are six possible combinations of bread, meat, and cheese. There would be the same six combinations for wheat bread. Twelve combinations are possible, and you can easily follow the tree to list each one.

If 3 cards are chosen from a standard deck what is the probability that you will pick a five a red card and a face card?

This is more complex than it seems as you have to account for red fives and red face cards.

So it's the sum of the chances of drawing:

2/52 black 5, 20/51 red, 12/50 face

OR

2/52 red 5, 19/51 red, 12/50 face

OR

4/52 any 5, 6/51 red face, 11/50 face

(2/52)*(20/51)*(12/50) + (2/52)*(19/51)*(12/50) + (4/52)*(6/51)*(11/50) =

(480 + 456 + 264) / 132600 = 1200/132600 = 0.905%

How many five card hands chosen from a standard deck contain two clubs and three hearts?

There are two smaller problems in this one. First, is the fraction formed by the probabilities of the cards desired, then also there's the permutations of this fraction. Multiplying them together gives the total probability.

The permutations of the clubs and hearts in the hand are 4 + 3 + 2 + 1 = 10. Just for justification, there is (CCHHH), (CHCHH), (CHHCH), (CHHHC), (HCCHH), (HCHCH), (HCHHC), (HHCCH), (HHCHC), (HHHCC). So:

P(two clubs, three hearts) = 10 * (13 * 12 * 13 * 12 * 11) / (52 * 51 * 50 * 49 * 48) = 10 * (2432111132) / (29325272131171) = (11 * 13) / (16 * 5 * 49 * 17) = 143/66,640

Do outcomes have the same chance of occurring?

No. Not all outcomes are equally probable. Generally, the chance, or probability, of a particular event happening can be calculated.
It should be noted that the possibility of some events happening cannot be calculated.

Which value shows a greater probability that the result did not occur by chance 0.05 or 0.001?

In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.

In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.

How many red non face cards are there in a deck of 52 cards?

Red non-face cards are:

A, 2, 3, 4, 5, 6, 7, 8, 9, 10 of hearts

A, 2, 3, 4, 5, 6, 7, 8, 9, 10 of diamonds

20 in total

How many visually different arrangements can be made from the letters absolute?

Infinitely many. You could, for example, cut out images of the 8 letters and paste then on the wall facing you. Each letter can take infinitely many positions on that wall so you have infinitely many arrangements.

What is the probability of picking any red-colored card from a pack?

The answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked.

The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
