Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

How did meiosis explain Mendel's results?
Mendel's laws and meiosis provide the foundation for heredity.
What does find the size of the sample space mean?
A concept in probability theory which considers all possible outcomes of an experiment, game, and so on, as points in a space.
1 - the chance to draw 2 jacks - the chance to draw no jacks leaves you with the chance to draw just one by elimination.
1 - (1/3)*(1/3) - (2/3)*(2/3)
1 - 1/9 - 4/9
1 - 5/9
4/9
A fair coin is tossed 5 times What is the probability of exactly 1 head?
First, you find the probability of picking 1 in 5 disregarding order (combination).
5 C 1 = 5/1 = 5
Then you divide that by the possible number of outcomes which is 25.
5/ 2^5= .0195
How many different arrangements can be made with the word satellite?
Don't know you figure it out dope!
What is the normal layout of a standard two story house?
Usually the bedrooms and a bathroom are upstairs and kitchen dining, lounge and laundry are down stairs.
If you want a specific layout I think that would vary a lot.

If a die is rolled once what is the probability of rolling a 3 or 4?
Since there are two desired outcomes out of six - the probability becomes 2/6 or 1/3.
I'd say it is rather 2/6 or 1/3...
What is the probability of 6 members of one family being born on a different day of the week?
Births are not distributed uniformly over days of the week: there are fewer births at weekends.
However, if you do assume that the distribution is uniform, then the probability is 6!/76 = 5040/117649 = 0.0428
Can standard deviation be above 10?
Yes, depending on the data being studied. Standard deviation can be thought of as the magnitude of the average distance between the data points and their mean.
If a dice is rolled what is the probability that a 2 will come up?
there are 6 faces of the dice
so the answer is 1/6
two dice are thrown once. write all the possible outcomes. find the probability of getting:
(i) a total of 12
(ii) a total of 3
(iii) a total of 8
What is the probability of rolling a number that is divisble by 3 or a 5?
Rolling a single die:
Six values are possible. Only five is divisible by five; both three and six and divisible by three; making three possibilities. Therefore, the required probability is 3/6 = 0.5.
A 1000 marbles weigh 2.47kg how much does 1 marbles weigh?
1 kilogram weighs 1000 grams
so 2.47 kilograms = 2470 grams
If 1000 marbles weigh 2470 grams then 1 marble weighs 2470/1000 = 2.47 grams
Does the past outcomes of coin flips greatly affect the outcome of future coin flips?
No. That is false.
What is the probability with a single die to roll less than seven?
Pretty good. A single die has six sides and they are normally numbered 1 to 6.
Since all values are under 7, their is a 100 percent probability of rolling less than 7.
How many times will it show a 3 if you rolled a die 260 times?
The probability is about 43 times, though you cannot be certain, so there is no definitive answer.
FALSE. The probability of success (or anything else) cannot be greater than 1.0
