What does or and probably mean?
There is probably a very important difference between the words and and or. This means that the result must satisfy both conditions at the same time. Or means that the result must match one condition, another condition, or both.
What is the OR rule in probability?
This is where the OR rule can help us when two outcomes are mutually exclusive. Mutually exclusive means that two outcomes of the same event cannot occur simultaneously. … If the events are mutually exclusive and we want to know the probability of one event OR the other occurring, we can use the OR rule.
What does probability mean when it says or?
O Probability: what it means
However, in the world of probability, OR means “either…or maybe both”. It’s not exclusive, or as is often the case in spoken English, choosing one means you won’t get the other. Instead, you can have both events and it still counts as OR.
What do you do with probability or probability?
When performing an OR operation, all result sets are concatenated, which can be thought of as addition. “Or” and “e” should be considered operations on (partial) results, not multiplications or additions.
What is the OR rule in probability?
This is where the OR rule can help us when two outcomes are mutually exclusive. Mutually exclusive means that two outcomes of the same event cannot occur simultaneously. … If the events are mutually exclusive and we want to know the probability of one event OR the other occurring, we can use the OR rule.
Is it or does it mean addition in probability?
P(A or B) = P(A) + P(B) Addition Rule 2: When two events, A and B, are not mutually exclusive, there is some overlap between the events. The probability of occurrence of A or B is the sum of the probability of each event minus the probability of coincidence. P(A or B) = P(A) + P(B) P(A and B)
What or in the statistics?
The odds ratio (OR) is a measure of the relationship between exposure and outcome. OR is the probability of an outcome occurring with a given exposure versus the probability of an outcome occurring without that exposure.
Does it mean probability or addition or multiplication?
In a nutshell (not always 100% correct!) The word o probably means addition, while u means multiplication. Aggregate Assumptions: You can only add if two events do not overlap. You can only multiply if the two events are independent.
And does this mean add or multiply?
It makes a lot of sense to think of “e” as Boolean multiplication. For “A and B”, where A and B are true (non-zero) or false (0), “e” is a multiplication.
What does y/or mean in math?
In English, most people use the word “or” to mean “exclusive or”. … In mathematics, the word “or” means “one or the other or both.” twenty
Means and multiplications in statistics?
It does not mean multiply.
