How many times does a digital cycle repeat in MHz?
MHz (megahertz) means millions of cycles per second. For example, if something has a frequency of 100 MHz, something will repeat at a rate of 100 million cycles per second.
If this is regarding probability, there are two cases:
E[Y] = (Summation) yp(y) in the discrete case. For example a fair dice has 1/6 probabilty for each event (of getting one value). so the sum is from 1 to 6 of yp(y). = 1(1/6) + 2(1/6) + 3(1/6) + 4(1/6) + 5(1/6) + 6(1/6) = (1/6) ( 1+2+3+4+5+6) = 21/6 = 3.5. So E[Y] for a fiar dice is 3.5
E[Y]= (intergral from -infinity to infinity) yf(y)dy , where f(y) is the density function for the continuous case. The integral must exits to be evaluated.
The difference between the two is basically the domain. If you dealing with integers you can use the discrete case, if you dealing with real numbers you have to use calculus.

Who uses pascals triangle nowadays?
Well Pascal doesn't use it much. Math people and maybe a few scientists.
It is a probability from 1 that it will happen to 0 that it will not happen
How many vehicles can a state license if it uses 3 letters and 3 digits on each tag?
If the letter and digits can be repeated and numbers like 0xx, 00x, and 000 are allowed then we see that the First Letter can be picked in 26 ways Second Letter can be picked in 26 ways Third Letter can be picked in 26 ways First Digit can be picked in 10 ways Second Digit can be picked in 10 ways Third Digit can be picked in 10 ways So total number of unique licence plates subject to above suppositions is 26 x 26 x 26 x 10 x 10 x 10 = 17576000
What characteristics do data sets share when they have the same range?
The minimum and maximum are the same.
The mean, median, and mode can be different.
1/12
What is the probability of a independent event is going to happen?
If it's an independent event then it's probability does not depend on preceding events. For example, if I flip a coin twice the probability that the coin will show 'heads' the second time is independent of what happened the first time; it's just 1/2.
What are the odds of rolling less that a 4 when rolling a die once?
if you rollid a die once the odds of getting less than four would be 3/6 or 50%.
What is the probability of rolling a seven in any combination on a pair of dice?
6/36 which is equal to 1/6
What graph what I used to show the height of four planets?
You what use a pie graph because of planets is round, four planets is like 4,000 feets because a planet is like 1,000 feets heigh
How many miles are there in 2591648 yards?
There are 1760 yards in one mile. Therefore, 2591648 yards is equal to 2591648/1760 = 1472.527 recurring (that is, 1472.5272727...) miles.
When finding the outcome on a dice do you times the probability together?
yes you times it then simplify
Does a sparkline include all the chart titles and axes labels like a regular chart?
No it doesn't. It is only a very small chart, fitting in a cell beside another cell. With the limited size it is not practical to put any other elements into it. Normally its location, being close to the values it is using, will tell you what it relates to.

What is the probability of rolling a 1 with six dice?
The probability of rolling at least one '1' with six dice is 66.5% [1-(5/6)^6]*100%
What is the formula for finding numbers within two standard deviations of a mean?
The numbers must be greater than (mean - 2*sd) and laess than (mean + 2*sd).
