Probability

Be nice, speak politely, keep yourself looking clean and look like your trying to get somewhere in life.

Yes I did! in the early sixties. I remember going to the neighborhood grocery store in So. Cal. and my mother purchasing a pair for 13-15 cents in summertime for all us kids.

Thrice means three times as many. If you have two green balls, it would mean you have six red balls.

What? Pyrrho died more than 18 Centuries before Descartes!

infinitely. I would recommend that you word this question exactly how you read it, so you can get a proper response.

If X is a discrete variable then

E(X) is the sum of x*Prob(X = x) where the summation is over all possible values of x.

It is like a dighram

a Picture to describe a problem

The pattern is add 2, add 4, add 6, add 2, add 4, add 6 and so forth. Based on this pattern the next number is 39.

1/5 of 10 = 2.

The answer depends on what you are looking for: the full sequence of results, the number of heads (or tails) the number of runs, the lengths of runs, or whatever.

6 people multiplied by 6 different chairs meaning there are a total of 36 different combinations because each chair has 6 different combinations.

If you have 6 chairs in a row, and 6 persons are going to be seated in those chairs,

the number of different arrangements (permutations) the 6 people can be seated

is 6! (six factorial):

6! = 6x5x4x3x2x1 = 720

i.e.,

The first person to sit has 6 options. For each option of the first person the second

has 5 options. For each option of the second person the third has 4 options. And so

on.

The risk.

A decathlon is 10 events, deca means 10, think of decade, or decameter (10cm)

As of now, creating an actual "Infinite Improbability Drive" as seen in Douglas Adams' "The Hitchhiker's Guide to the Galaxy" is purely fictional and not feasible in reality. It exists as a humorous and nonsensical concept in the realm of science fiction.

There are just two ways to get the value of 11 when dice are thrown. one would be a 5 and 6 and the other is a 6 and 5.

The probability of getting a red card out of a standard 52 card deck is 26 in 52, or 0.5. The probability of getting a second red card is 25 in 51, or 0.490, because one red card is missing, and the deck is short by one card. The probability of getting a black card next is 26 in 50, or 0.52, because the deck is short by two cards, but all the black cards are there. Multiply these probabilities together, and you get about 0.127, or about 1 in 8, so the probability of getting 2 red cards and then a black card in a random 52 card deck is about 1 in 8.

They are independent events.

When rolling 2 dice there are 36 combinations that can occur.

Sums will range from 2 to 12; sums divided by 4 are 4, 8, and 12

You can get this by dice combinations of

1 3

3 1

2 2

4 4

2 6

6 2

3 5

5 3

6 6

That is 9 ways. so odds are 9/36 = 1 in 4

Saliva sample testing is a technique used to collect samples of a person's saliva, or spit, to check for or monitor certain drugs, hormones (chemical messengers from one cell or group of cells to another), antibodies

D = diagonal, S = side, P = perimeter

S = D/sqrt(2)

P = 4S = 4D/sqrt(2)

So, for this problem:

P = 48/sqrt(2)

To the nearest tenth, this is 33.9 inches

Yes it is; the answer is 1.

None. Aces are playing cards that are usually very much smaller that the measurements given. Or they are services in games that cannot be returned and so are winners. However, these cannot be measured in terms of the square footage. Or they can be people who are champions in their field but again, these would not be measured in square feet.

45 sequences. Make it easier and think what are the 2 tail flips. They are: 1-2; 1-3;1-4...1-10. That is 9 sequences starting with 1. There are 9 sequences starting with 2, 9 starting with 3, etc, up to 10. That makes 90 sequences, but since 1-2 is the same as 2-1, ie order doesn't matter, divide that in half to get 45.
