Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
And we want to find this probability:
Part b fewer than 10 will check bags
We want this probability:
We can use the complement rule and we have:
And we can find the individual probabilities like this:
And replacing we got:
Part c at least 10 bags
We can find this probability like this:
And replacing we got 0.825
<u>Answer:</u>
A. $33,333.33
<u>Step-by-step explanation:</u>
This is the amount which the owner should have had at the time of loss:
80% of $90,000 = $72,000
But instead of $72,000, the owner had only $40,000.
It means that the owner had maintained of the totoal amount of insurance he should have had.
Therefore, the company will pay of the amount of loss.
The correct answer option is A. $33,333.33.
