  ## What does and/or mean in math?
  
  In mathematics, the word “or” means “one or the other or both”. Therefore in logic, “or” includes the case when both atomic parts of the state are true.
  
  ## Does and mean plus in math?
  
  The plus and minus signs, + and −, are mathematical symbols used to represent the notions of positive and negative, respectively. Plus and minus are Latin terms meaning “more” and “less”, respectively.
  
  ## Is and add or multiply?
  
  If all the events happen (an “and question”) Multiply the probabilities together. If only one of the events happens (an “or question”) Add the probabilities together.
  
  ## What does and mean in math probability?
  
  In probability, there’s a very important distinction between the words and and or. And means that the outcome has to satisfy both conditions at the same time. Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time.
  
  ## What is the and/or sign?
  
  “And/or” is just called “or” and is represented as ∨, from the Latin vel meaning or. But note that it’s a separate symbol from the letter “v”, though similar. In contrast, “or” in the sense of “this one or that one but never both” is called “exclusive or” or “xor” and can be symbolized as ⊻ or ⊕.

  ## Does * mean multiply?
  
  The asterisk symbol or * usually means to multiply. Sometimes, the * can represent other mathematical operators. In regular multiplication, 1 * 2 = 2.
  
  ## Does mean multiply?
  
  In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem. Here is another example of a multiplication fact that shows multiplication is also repeated addition.
  
  ## What does 2 plus signs mean?
  
  Filters. The symbol (+), as in 2 + 2 = 4, that is used to indicate addition or a positive quantity. noun.
  
  ## What is the general multiplication rule?
  
  The multiplication rule is a way to find the probability of two events happening at the same time (this is also one of the AP Statistics formulas). The general multiplication rule formula is: P(A ∩ B) = P(A) P(B|A) and the specific multiplication rule is P(A and B) = P(A) * P(B).
  
  ## Do you add or multiply dependent events?
  
  When we calculate probabilities involving one event AND another event occurring, we multiply their probabilities. We call these dependent events. In other cases, the first event happening does not impact the probability of the seconds.
  
  ## Do you add or multiply mutually exclusive events?
  
  Mutually Exclusive Events If two events are disjoint, then the probability of them both occurring at the same time is 0. If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring.
  
  ## What does or mean in logic?
  
  Basic logic symbols
  
  ∨ + ∥ logical (inclusive) disjunction or
  ⊕ ⊻ ≢ exclusive disjunction xor; either or
  ⊤ T 1 Tautology top, truth
  ⊥ F 0 Contradiction bottom, falsum, falsity

  ## What are the 3 types of probability?
  
  Three Types of Probability Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes). Relative Frequency Definition. Subjective Probability.
  
  ## What does at least mean in probability?
  
  At least also means “less than or equal to”. Therefore, in probability, at least mean the minimum value that should occur once a random event happens.
