You take a quiz with 6 multiple choice questions. After you studied your estimated that you would have about an 80 % chance of g
Arada [10]

Answer:

1.15%

Step-by-step explanation:

To get the probability of m  independent events you multiply the individual probability of each event. In this case we have m independent events, each one with the same probability, therefore:

p^{m}

0.8^{20} = 1.15\%

This is a particlar scenario of binomial distribution problem. So the binomial distribution questions are about the number of success of m independent events, where every individual event has the same p probability. In the question we have 20 events and each event has a probability of 80%. The binomial distribution formula is:

\binom{n}{k} * p^{k} * (1-p)^{n-k}

n is the number of events

k is the number of success

p is the probability of each individual event

\binom{n}{k} is the binomial coefficient

the binomial coefficient allows to find the subsets of k elements in a set of n elements.  In this case there is only one subset possible since the only way to get 20 of 20 correct questions is to getting right all questions (for getting 19 of 20 questions there are many ways, for example getting the first question wrong and all the other questions right, or getting second questions wrong and all the other questions right, etc).

\binom{n}{k} = \frac{n!}{k!(n-k)!}

therefore, for this questions we have:

\frac{20!}{20!(20-20)!} * 0.8^{20} * (1-0.8)^{0} = 1.15\%

Dominic's water jug holds 1.25 quarts. Terrell says he can find the capacity of the jug in fluid ounces by dividing 1.25 by 32.
IceJOKER [234]
No.  Terrell is not correct.  Terrell is incorrect.  The method he offers is
inappropriate, inapplicable, and lacks veracity, and as a mathematician,
Terrell himself is devoid of integrity.  If his method is implemented, it
cannot accurately compute the capacity of Dominic's water jug in fluid
ounces.  It will produce a number that is inaccurate, fallacious, mistaken,
erroneous, and incorrect.  Moreover, the solution will be wrong.

If the units are carried through with the calculation ... as always they must ...
then it will immediately become clear that Terrell's method has produced a
solution with units of  "square quarts per ounce", whereupon any witnesses
should justifiably become nauseous.  Terrell's method should be disdained,
rejected, discarded and ignored.

==> 1.25 should not be "divided" by 32. 

==> Instead, 1.25 should be multiplied by 32.

The modified method will produce a result with units of "fluid ounces" ...
the first indication to the assembled multitude that whatever the number
is, there is a reasonable chance that it could be a correct one.
