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.

When are two events considered to be independent?
The outcome of either event does not depend on the outcome of the other.
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.
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 getting two even numbers when rolling two dice?
The odds are 1:3. The probability is 1/4 or 25%.
Odds of rolling a 7 twice in a row on craps?
Odds of rolling seven once (2 dice) is 1:6, twice in a row, odds are 1:36. The reason is- the first die can be any number, but the second die must be a particular number. For example, if the first die is 6, then the second die has to be 1 to make 7. When an event occurs twice, and the two events are unrelated, then you can multiply the odds together= 1/6 * 1/6 = 1/36.
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.
