Canceling units is also called unit analysis.
This is also called dimensional analysis.
What is a unit of analysis in statistics?
- The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
- Because it is the analysis you do in your study that determines what the unit is.
- For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.
For example -
1 ft = 12 in
3 ft =
3 ft = ( 3 * 12 ) in ⇒ 36 in

Answer:
A) 0.1612
B) 0.8031
C) 0.1969
Step-by-step explanation:
For each toss of the die, there are only two possible outcomes. Either it is a 3, or it is not. The probability of getting a 3 on each toss is independent from other tosses. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
Five tosses, so
The die has 6 values, from 1 to 6. The die is fair, so each outcome is equally as likely. The probability of a 3 appearing in a single throw is
(a) twice
This is
(b) at most once
(c) at least two times.
Either a 3 appears at most once, or it does at least two times. The sum of the probabilities of these events is decimal 1. So
We want
So
