Binomial Probability Formula Binomial Probability Formula Binomial probability is defined as the probability of an event in which its outcomes can be broken down into two probabilities p and q, where p and q are complementary (i.e. p + q = 1) For example, tossing a coin can be either heads or tails, each of which has a (theoretical) probability of 0.5. Rolling a four on a six-sided die can be expressed as the probability (1/6) of getting a 4 or the probability (5/6) of rolling something else. Such experiments are known as Bernoulli trials. Binomial probability formula for determining the probability of achieving exactly k successes in n trials is shown below. You haven't given any values, but that's ok, just use the formula: P(r) = p^r * q^(n-r) * C(n,r) This will find the probability of "r" successes. p = the probability of success on any trial q = probability of failure on any trial (also = 1 - p) n = number of trials If you want to find a range, find the probabilities for all successes in that range, and add them. more info: keep in mind that C(n,r) = nCr = (n!) / ((n-r)!*r!)

For an example, let's say that you're trying to find the probability of 5 successes: P(5) = .2^5 * .8^1 * C(6,5) P(5) = .001536 If you're trying to find the probability of atleast 5 successes, add P(5) to P(6): P(x>=5) = P(5) + .2^6 * .8^0 * C(6,6) P(x>=5) = .001536 + .000064 = .0016  What the heck, I have a program that does all these, so I'll give you all 7 probabilities for the individual values: Value, Probability: P(0) = .262144 P(1) = .393216 P(2) = .24576 P(3) = . 08192 P(4) = .01536 P(5) = .001536 P(6) = .000064 Binomial is deals with the polynomial that has two terms is known as a binomial e.g.5x + 3y, 2x2 â€“ 5xy.Probability is the arithmetical quantify of the possibility of an event to occur. If in an examine there are n feasible ways completely and mutually exclusive and out of them in m ways in the event A occur, it is given by (m / n) if in a random sequence of n trails of an events, M are favor to the event, then ratio is (M / n).by studying in both combined as binomial probability as P(A) = m / n. The possibility of an event can be conveyed as a binomial probability if its conclusions can be wrecked down into two probability of p and q, where p and q are balancing (i.e. p + q = 1) Binomial Probability Formula A Random Experiment is an experiment, which satisfies three following conditions. There are two or more outcomes Every outcome is uncertain The experiment can be repeated any number of times under similar conditions. Example 1: Tossing a coin In the cases of tossing a coin, there are two outcomes, both of which are uncertain. Also we can toss a coin any number of times under similar conditions.

What is a Line Plot What is a Line Plot Line plot is a statistical graph which represents the data recorded in experiments or surveys. Line plots are used for the quick analysis of data and this shows the range, minimum and maximum and also shows the exact values retained for the given set of values. A line plot shows the given data on a number line where the values are marked as x or any other symbol and they show the frequency. Line plot is very simple and easy to construct. Line plot definition states that it collects and classifies the data very fast. Constructing a Line Plot Line plot is a collection of frequency of data and it is known as graph as it shows frequency of the length of the number line. It is said to be very easy and the fastest way to organize the data. On the basis of number sources the dataâ€™s should be collected. Here is the stepwise construction of line plots: Step 1: Whether you will first demonstrate the scale which is to be used. If all the scales in the data is measured to be 0 to 10. Math.Tutorvista.com

Step 2: Draw a horizontal line in the paper. Step 3: Divide the drawn horizontal line into two same parts. Step 4: List the dataâ€™s which is given and note X on the correct number In the line plot, some example problems are given below to find the line plots. If the students will see the below picture of the line plot. They will know how to draw the line plots. First, draw a horizontal line in a paper and then mark the values in the line. Mark the value X above the corrected number. Example 1: Draw the line plot by using the following data. 1, 4, 3, 2, 1, 4, 2, 3, 2, 5, 3, 2, 1, 5, 4, 3 Solution : Given : Data = 1, 4, 3, 2, 1, 4, 2, 3, 2, 5, 3, 2, 1, 5, 4, 3 Example 3: Draw the line plot by using the following data: 1, 3, 2, 3, 2, 2, 4, 5, 4, 3, 2, 1, 5, 4, 2, 1 Solution : Data: 1, 3, 2, 3, 2, 3, 4, 5, 4, 3, 2, 1, 5, 4, 2, 5
