Answer:

f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}

Step-by-step explanation:

Recall that a <em>probability mass function</em> defined on a discrete random variable X is just a function that gives the probability that the random variable equals a certain value k

f_X(k)=P(X=k)

In this case we have the event  

“The computer will ask for a roll to the left when a roll to the right is appropriate” with a probability of 0.003.

Then we have 2 possible events, either the computer is right or not.

Since we have 4 computers in parallel, the situation could be modeled with a binomial distribution and the probability mass function

f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}

This gives the probability that k computers are wrong at the same time.

Which of the following properties will most likely have the lowest
victus00 [196]

The correct answer is A: a steel building.

Explanation:

A steel building will have the lowest premiums out of all the choices given above. After reading several insurance companies policies, a steel building has premiums 30% lower than any other homeowner policy. Steel is harder to destroy in a fire and the damage would be less than a wood home, mixed composition, or even an all brick home.  

A wood home has the highest premiums out of all the choices given. When one catches on fire, they will burn fast and usually is a total loss unless the fire trucks get there in minutes.

A brick home can still be destroyed by fire on the inside even if the damage is minimal on the outside of the home.

A mixed composition home, will also be damaged by fire and could be a total loss unless fire trucks are there within minutes.
