Sum Rule:
P(A) = \sum_{B} P(A,B)
Product Rule:
P(A , B) = P(A) P(B|A) or P(A, B)=P(B) P(A|B)
[P(A|B) means probability of A given that B has occurred]
P(A, B) = P(A) P(B) , if A and B are independent events.

What is the probability that the sum of the faces is 7?
The probability that the sum of two dice is 7 is 6 in 36, or 1 in 6.Of all the combinations, this is the one with the highest probability.
When rolling two dice what is the probability the sum is greater than 1?
The probability is 1.
In the discrete probability distribution what is the sum of all probabilities?
The sum should equal to 1.
What is the probability that the sum of the numbers from two rolled dice result in a perfect square or even number?
Part1: Finding probability of getting sum as a perfect square. Maximum sum of both the dice is (6+6) equal to 12. Up to 12, the perfect squares are: 1, 4 and 9. Getting a sum of 1 from two dice is not possible. So, we are left with 4 and 9. To get 4, the combination can be: (2,2) or (1,3) or (3,1). This means, to get the sum as 4, the probability is [3/36]. To get 9, the combination can be: (3,6) or (6,3) or (5,4) or (4,5). This means, to get the sum as 9, the probability is [4/36]. Therefore,the total probability of getting the sum as a perfect square is: [(3/36)+(4/36)]=[7/36]. Part2: Finding the probability of getting sum as an even number. The possible even numbers can be 2, 4, 6, 8, 10 and 12. But, as 4 is already considered in part1, it should be ignored in this case. The probability of getting sum as 2 is: [1/36] The probability of getting sum as 6 is: [5/36] The probability of getting sum as 8 is: [5/36] The probability of getting sum as 10 is: [3/36] By adding all the above, the probability of getting sum as an even number (ignoring 4) is: [(1/36)+(5/36)+(5/36)+(3/36)]=[14/36]. From part 1 and part 2, we get the total probability as [(7/36)+(14/36)]=[7/12]=0.583333.
If two fair dice were rolled what is the probability of them rolling a sum of six?
If you rolled 2 fair dice, the probability of having a sum of 6 is 5 over 36
Definition of the Product rule in genetics?
States that the joint probability of two independent events is the product of their individual probabilities
What is the sum of probability that something will happen and the probability that something will NOT happen?
The sum is 1
What is a sum in probability?
The sum of the probability of success and the probability of failure had better equal 1.00 (100%) or an error has been committed.
What is the probability that the sum is a prime number?
The answer depends on the sum of WHAT!
What is the probability that the sum of the faces is 7?
The probability that the sum of two dice is 7 is 6 in 36, or 1 in 6.Of all the combinations, this is the one with the highest probability.
When two dice are rolled find the probability of getting a 6 or 7?
Probability that the sum is 6 = 5/36 Probability that the sum is 7 = 6/36
What does describes the product rule?
Product Rule This question is within the Cells and Genetics category which calls for defining this question not in the calculus field, but within obviously the genetics area. Product Rule: The probability of an combined event individually in a combined event.
What is the probability of not rolling sum of 6 with two fair dice?
The probability of not rolling a sum of six with two fair dice is 1 minus the probability of rolling a sum of six. There are 36 permutations of rolling two dice. Of these, five sum to six, 1+5, 2+4, 3+3, 4+2, and 5+1. The probability, then of rolling a sum of six is 5 in 36. The probability, then of not rolling a sum of six is 31 in 36, or about 0.8611.
What is a probability distribution for rolling 3 dice?
The answer depends on the probability distribution of WHAT variable. The variable could be the sum or the product of the three numbers, the maximum, minimum, the mean, median, number of 3s, number of primes, and so on.
Why is it that the product of sum is binomial?
It depends on the product of sum of what.
What is the probability of rolling a sum of 10 or a sum that is an odd number when two number cubes are rolled?
The probability is 21/36 = 7/12
What is the probability of rolling the sum of two if you roll a pair of dice sixty times?
The probability of getting a sum of 2 at least once is 0.8155
