There are two possible sums that add up to a number evenly divisible by 2 and 3, namely 6 and 12.
There are 5 different ways to roll a sum of 6, so the probability of that happening is 5/36.
There is 1 way to roll a sum of 12, so the probability of that happening is 1/36.
The probability of either happening is the sum of the two separate probabilities.
p=5/36+1/36=6/36=1/6 ~= .1667 = 16.67%

An experiment consists of rolling two fair dice and adding the dots on the two sides facing upwhat is the probability that the sum of the dots is divisible by 2 and 3?
2/9!
The probability of obtaining a sum greater 8 or less than 6?
The answer depends on what the experiment consists of. Since that is not specified, there can be no sensible answer.
An experiment consists of flipping a coin and then rolling a die What is the probability of observing a head on the coin or a 3 on the die?
The probability of flipping a Head is the same as that for a Tail and is 1/2 or 50%. The probability of rolling a particular number on a die is 1/6 since there are 6 numbers. Combining these two probabilities (by multiplication) we have, as the combined probability 1/2 x 1/6 = 1/12 = 0.0833333333333333(the 3 recurs) which as a percentage is 8.33333333333%
What is the sample space for choosing the letter from the word probability?
The sample space consists of the letters of the word "PROBABILITY" = {P,R,O,B,A,I,L,T,Y}

What is the probability of having a family of ten?
If the family consists of a pair of parents and their offspring, then the probability is very close to 0.

What is an example of a binomial experiment?
A binomial experiment is a experiment that consists of repeated trails, with two possible outcomes. An example of this would be a coin toss.Ê
Is it true or false that a number is divisible by 6 if and only if it is divisible by 3?
False. The question consists of two parts: - a number is divisible by 6 if it is divisible by 3? False. It must also be divisible by 2. - a number is divisible by 6 only if it is divisible by 3? This is true but the false part makes the whole statement false.

A committee consists of 7 women and 4men if a member of the committee is chosen at random to act as chairperson what is the probability that the choices is woman?
The probability of a woman being chosen in this situation is 7/11.
What is a probability of an event?
Lets first start by defining some terms:Probability (P) in statistics is defined as the chance of an event occurring.Probability experiment is a chance process that leads to results called outcomes.An outcome is the result of a single trial of a probability experiment.A sample set is the set of all possible outcomes of a probability experiment.An event consists of a set of outcomes of a probability experiment. An event can be one outcome or more than one outcome. The event can be anything from flipping a coin, to rolling a die, to picking a card.The probability of any event (E) is:(# of outcomes in E) / (total # of outcomes in sample space)For example: Find the probability a die is rolled and you get a 4?We know that there are 6 possibilities when rolling a die. We can either rolled a 1, or a 2, or a 3, or a 4, or a 5, or a 6.Using the equation above:P(rolling a 4)= 1/6The event in this case is rolling a 4.
A committee consists of 7 woman and 4 men what is the probability that the choice is a woman?
7/11Note:Choosing people in a committee is not a matter of chance or probability. Personality, skill, seniority etc. enter into the decision.
