Why the probability of success decreases when we repeat the same experiment several times?

It does not, so the question is based on a misunderstanding of probability.

What symbol is used for probability of success in statistics?
A "p" is used for probability of success. A "q" is used for probability of failure.
What is the symbol for probability of success in a binomial trial?
The symbol for probability of success in a binomial trial is the letter p. It is the symbol used for probability in all statistical testing.
Is binomial probability distribution always negatively skewed?
No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.
What are four requirements for binomial distribution?
A binomial experiment is a probability experiment that satisfies the following four requirements:1. Each trial can have only two outcomes or outcomes that can be reduced to two outcomes. These outcomes can be considered as either success or failure.2. There must be a fixed number of trials.3. The outcomes of each trial must be independent of each other.4. The probability of a success must remain the same for each trial.
How do you solve for probabilities in binomial distributions?
Suppose you have n trials of an experiment in which the probability of "success" in each trial is p. Then the probability of r successes is: nCr*pr*(1-p)n-r for r = 0, 1, ... n. nCr = n!/[r!*(n-r)!]
What are the requirements for the binomial probability distribution?
The requirements are that there are repeated trials of the same experiment, that each trial is independent and that the probability of success remains the same.
What are the benefits of integrating safety into the Army mission?
It increases the probability of mission success.
A machine produce 100 items assuming that 10 of the items are defective what is the probability tha random sample of size 5 from the out put will contain 3 defective items?
in a certain statistical experiment, the probability of a success is 0.20. if the experiment is conducted 80 time, what is the probability of getting 20 successes or more?
Can a binomial experiment be used to find the probability of 4 outcomes of .20 and 16?
If the question is about 4 successful outcomes out of 16 trials, when the probability of success in any single trial is 0.20 and independent of the outcomes of other trials, then the answer is, yes, the binomial experiment can be used.
What symbol is used for probability of success in statistics?
A "p" is used for probability of success. A "q" is used for probability of failure.
What is the formula for geometric probability?
If you have an experiment in which the probability of success at each trial is p, then the probability that the first success occurs on the nth trial is Pr(N = n) = [(1 - p)^(n-1)]*p for n = 1, 2, 3, ...
The probability of success is determined by the probability of failure and vice versa?
Yes, but only if there are only two outcomes for an experiment: success and failure. If there are more than two outcomes possible, for example Win, Draw or Lose, the outcomes have to be grouped so that the assertion in the question remains valid. Also, note that in everyday use there is a positive connotation for the word "success". This is not the case in probability theory. If you want the probability of a person being killed by a lightning strike, then success requires thaa person being killed. I somehow don't think the person would consider that a "success".
What is a binomial distribution?
The binomial distribution is one in which you have repeated trials of an experiment in which the outcomes of the experiment are independent, the probability of the outcome is constant.If there are n trials and the probability of "success" in each trail is p, then the probability of exactly r successes is (nCr)*p^r*(1-p)^(n-r) :where nCr = n!/[r!*(n-r)!]and n! = n*(n-1)*...*3*2*1
A binomial probability distribution with 5 as the probability of a success will have a distribution with a shape best described by?
Nothing since it is impossible. No event can have 5 as the probability of success.
What is the symbol for probability of success in a binomial trial?
The symbol for probability of success in a binomial trial is the letter p. It is the symbol used for probability in all statistical testing.
Is binomial probability distribution always negatively skewed?
No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.No. It depends on the probability of success, p. If p < 0.5 the distribution is positively skewed.
What are the features of a binomial distribution?
An experiment with only two outcomes ("success" and "failure"), a constant probability of success, a number of independent trials. Then, if the probability of a success in a trial is p, the probability of r successes in n trials is nCr*pr*(1-p)(n-r) for r = 0, 1, 2, ..., n. In case the super-and sub-scripts do not work, that is n!/[r!*(n-r)!]*p^r*(1-p)^(n-r)
