Probability

Assuming the faces are numbered 1 to 12, and the die is fair, the mean value is 6.5

red or black

since there is only one Ace of Spades and 52 cards in a deck the probability would be 1/52.

32.6% or 67.4% depending on what probability you want.

First of all I try to find out what the game is! The rest of the answer depends on the answer to the above question!

The theoretical probability provides a model for predicting the outcome of trials. You then carry out a number of trials. Compare the outcome of your trials with the results predicted by the theoretical model. The comparison will usually involve "hypothesis testing", a branch of statistics. This is a method to test how likely the actual outcomes are if the theoretical probabilities were true. The exact nature of the test will depend on the theoretical basis and so the answer cannot be simplified.

if twins run in the family u are more likely to have twins but most likely fraternal because identical twins are just a very unique coincidence

Since in the word "party" no letters are repeated, the letters can be arranged in 5! ways, or 120.

It is 0.1389 approx.

Most people will answer this by explaining that the twins will run the same risk are normal adults.

However, if the twins are monozygotic they may also be "mirror-twins", in which one twin would have an increased chance of displaying situs inversus, a condition where the organs are flipped (mirrored to other twin).

This in and of itself isn't harmful, but the origins of situs inversus are believed to be in the earliest stages of development, arising from cilia that move clockwise instead of counter-clockwise, thus moving the cells that will form organs to the wrong side.

Going back to questions of infertility, it is known that this wrong-turning cilia cannot play a normal roll in some biologic functions, including driving the bending movement required for sperm (cilia structures of the tail) to be motile. In this way, male infertility (sterility) could theoretically be affecting at a higher incidence in man mirror twins with situs inversus.

It is another name for the Gaussian distribution.

Nope! definitely not 2.. The answer should be 126 I'm looking for the solution. Eg. Q. How many 4 digit numbers can be made from the digits 1-9 A. 9X8X7X6= 3024.

Everything that is normal and can can be distributed easily is known as normal distribution time.

It depends on how many shelves there are, which you did not specify. Please restate the question.

Assuming that there are just 2 shelves with 21 books on each, then the 21 books on the top shelf can be arranged in factorial 21 different ways, with the same result for the lower shelf. To find "factorial 21", which is written as 21! the calculation required is 21 x 20 x 19 x 18....and so on all the way down to ...x 3 x 2 x 1! However, with access to a scientific calculator the result for 21!can be found by first pressing the buttons for 21 followed by pressing the button labelled n!, which gives the result for 21! as 5109094217109440000 for each shelf. The result for the two shelves is 21! x 21! which is such a tremendous number that no-one could arrange books in that way if they spent their whole life at it (including from birth).

No.

5/6 as a fraction

Knowing the results in advance, there is a 7/10 chance that the first toss is heads.

In this case "seven out of ten" is quite literal. The first toss is one of the 10, and 7 of them came up heads, so 7/10 is the chance that this particular one is one of the heads.

One muffin said, "Flippin eck, its hot in here."
The other muffin looked across to baking tray and said "WOW! a talking muffin!"

ignoring the minute chance that it will land on it's side as well as assuming that the air resistance due to the different patterns in the coin is negligible the chance of a coin landing heads is 50%

in a factory that produces personal computers, standard costs are often used for direct materials, direct labor, and variable overhead, at the unit level. Resource usage that can be traced exactly to what is to be produced is referred to as direct.

The probability is 0.375

The requirements are that there are repeated trials of the same experiment, that each trial is independent and that the probability of success remains the same.
