Answer:
B. No. There is not a fixed number of trials
Step-by-step explanation:
Binomial random variable:
Can only have two outcomes(yes/no questions).
Each trial must be independent, that is, the probability of a success is always the same in a trial, and the number of trials is fixed.
It's probabilities must be between 0 and 1.
Is the number of passengers who pass through security in this time a binomial random variable?
For each person, there are only two possible outcomes. Either they are screened, or not. However, we don't want to know the number of people screened, which is binomial, we want to know the number of people until 10 are screened, which is inverse binomial. So, since there is not a fixed number of trials, this is not binomial, and the answer is given by option B.
Answer:
x=.1460
Step-by-step explanation:
ln5^(2x+1)=ln8
2x+1ln5=ln8
2x+1=(ln8/ln5)
x=((ln8/ln5)-1)/2
