Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
The probability of success is .06.
This means that
What is the probability of two successes in seven trials?
This is P(X = 2) when n = 7. So
The correct answer is given by option a.
Answer:
i think the answer is b hope hope this helps have a nice day please give me brainliest if correct :)
Step-by-step explanation:
Answer: 1068
Step-by-step explanation:
Formula of sample size :
, where p = prior population proportion , E = margin of error , = Critical z- value.
Let p = proportion of visitors who are repeat visitors.
Given : p=0.5
E= 3%= 0.03
critical z-value for 95% confidence = 1.96
Now,
[round to the next integer]
Hence, the required sample size = 1068
