Q. What if there is no mode in math?
To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The “mode” is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.
Q. What is the symbol for sample size?
Glossary of Symbols and Abbreviations
| y^x | y to the power of x (also seen as y**x or yx) |
|---|---|
| μ | mean of a population – see also |
| n | sample size (population sized is usually referred to as N) |

Q. What is the formula for basic probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space….Basic Probability Formulas.
| All Probability Formulas List in Maths | |
|---|---|
| Conditional Probability | P(A | B) = P(A∩B) / P(B) |
| Bayes Formula | P(A | B) = P(B | A) ⋅ P(A) / P(B) |
Q. What are the first three laws of probability?
There are three main rules associated with basic probability: the addition rule, the multiplication rule, and the complement rule.
Q. What are the two basic law of probability?
Additional and multiplication rules are two basic laws of probability.
Q. How many laws of probability are there?
Three Laws
Q. What are the 4 probability rules?
Keyboard Shortcuts
- Rule 1: The probability of an impossible event is zero; the probability of a certain event is one.
- Rule 2: For S the sample space of all possibilities, P(S) = 1.
- Rule 3: For any event A, P(Ac) = 1 – P(A).
- Rule 4 (Addition Rule): This is the probability that either one or both events occur.
- a.
- b.
Q. What is the multiplication law of probability?
Multiplication Rule Probability: Using the Specific Rule Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.
