If A and B are mutually exclusive event then Probability of A or B is P(A)+P(B).
If they are not mutually exclusive then it is that minus the probability of the P(A)+P(B)
That is to say P( A or B)= P(A)+P(B)- P(A and B). Of course it is clear that if they are mutually exclusive, P(A and B)=0 and we have the first formula.

What does either mean 8n probability?
In probability, "either" typically refers to the occurrence of one or more events from a set of possibilities. For example, in the context of two events A and B, "either A or B" means that at least one of the events occurs. This can include scenarios where both events occur, depending on the context and whether the events are mutually exclusive. The probability of "either A or B" can be calculated using the formula P(A or B) = P(A) + P(B) - P(A and B) if they are not mutually exclusive.
What is the formula for overlapping events in propoblilty?
The formula for the probability of overlapping events, specifically for two events A and B, is given by: [ P(A \cup B) = P(A) + P(B) - P(A \cap B) ] Here, ( P(A \cup B) ) is the probability that either event A or event B occurs, ( P(A) ) and ( P(B) ) are the probabilities of events A and B occurring individually, and ( P(A \cap B) ) is the probability that both events occur simultaneously. This formula accounts for the overlap by subtracting the joint probability to avoid double-counting.
Odds of rolling a sum of 11?
If you mean with two dice, you have two favorable events (6+5, and 5+6), out of a total of 36 combinations. Therefore, your probability is 2/36 = 1/18.
When are two events considered to be independent?
The outcome of either event does not depend on the outcome of the other.
What are the odds of rolling two ones on two 20-sided dies?
The odds of rolling a single one on a 20-sided die is 1 in 20 (1/20). Since the rolls are independent events, the odds of rolling two ones on two 20-sided dice would be (1/20) * (1/20), which simplifies to 1 in 400 (1/400).

What are the odds of rolling double six in dice-throwing?
This can be considered two independent Bernoulli events, so the probability of the whole is the product of the individual events, or (1/6)(1/6) = 1/36.
What are the odds of rolling two sixes?
The odds are 1:36
When two dice are rolled Fine the odds that the score on the dice is either 3?
To roll a three on any one dice, the odds are 1/6. To roll a three on any one of a pair of dice, the odds are 1/6 x 1/6 which is 1/36 or 1 in 36 chance.
