Answer:
a) np > 5
d) nq > 5
Step-by-step explanation:
Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial.
A binomial distribution can be approximated with the help of normal distribution.
A binomial distribution has parameters:
where n is the number of independent trials and p is the probability of success.
If p is the probability of success, then we define probability of failure as:
A normal distribution can be used to approximate the binomial distribution if
Thus, the correct answer is
a) np > 5
d) nq > 5
X = adult tickets and x+58 = student tickets
Create the equation from the problem.
x + x + 58 = 708
Combine like terms.
2x +58 = 708
Subtract 58.
2x = 650
Divide by 2.
x = 325
Therefore, your answer is:
there were 325 adult tickets sold.
(Adding 58 to that number will get you the student tickets sold which is 383 if they ask.)
108 is the answer to your question
Answer:
1 or 4/4
It is certain that the spinner will land on a number less that 5 because the selections are labeled 1 to 4 and the numbers 1 to 4 are less than 5.
