How do you name this digits 120000000000000000?
The number 120 000 000 000 000 000 is 120 quadrillion.
How do you work out the probability that a biased dice will land on a six is 0.35?
You roll it many times. The probability that it lands on a six is the number of times that it lands on a six divided by the number of times the die has been rolled.
The first digit can be any one of six. For each of these . . .
The second digit can be any one of the remaining five. For each of these . . .
The third digit can be any one of the remaining four.
Total number of possible arrangements is (6 x 5 x 4) = 120 .
But you used the word "combinations", which has a very specific meaning when
working with this type of exercise. "Combination" means a group of items that's
unique but the order in which they appear doesn't matter. If you're looking for
'combinations', then 123, 132, 231, 213, 312, and 321 are all the same combination.
In that case, there are only 20 unique 3-digit combinations from 6 digits. Each of those
can be arranged in 6 different orders, which gives you the '120' calculated above.
It means from the centre of one object to the centre of another. For instance, wall studs are usually 16 inches on centre. So, from the centre of one stud to the centre of the next stud it is 16 inches.

How do you calculate risk on a two-asset portfolio?
For a two-asset portfolio, the risk of the portfolio, σp, is: 2222p1122112212222p11221212121212σ=wσ+wσ+2wσwσρorσ=wσ+wσ+2wwcovcov since ρ=σσ where σi is the standard deviation of asset i's returns, ρ12 is the correlation between the returns of asset 1 and 2, and cov12 is the covariance between the returns of asset 1 and 2. Problem What is the portfolio standard deviation for a two-asset portfolio comprised of the following two assets if the correlation of their returns is 0.5? Asset A Asset B Expected return 10% 20% Standard deviation of expected returns 5% 20% Amount invested $40,000 $60,000

What is the difference between retesting and regression testing?
Retesting means testing the functionality or bug again to ensure the code is fixed. If it is not fixed, defect needs to be re-opened. If fixed, defect is closed.
Regression testing means testing your software application when it undergoes a code change to ensure that the new code has not affected other parts of the software.
