The answer is 1/3. Basically start at A, you go up one. Then count over to B and it's 3 spaces over, so you get 1/3.

it's D 1/3 cause your going up 1 and over 3 so that should give you a positive cause the line is going up instead of down . now on the other hand if the line was going down it would me -1/3 cause went down one and over negative three, but in ur case it's ↓

D.) 1/3

A company that translates books between various languages is currently testing a computer-based translation service. The founder of the company expects the computer program to make some errors, but then so do human translators. The computer error rate is supposed to be an average of 2 per 500 words of translation. Suppose the company founder randomly selects a 3,000-word passage. Assume that the Poisson distribution applies and that the computer error rate is actually 2 errors per 500 words. Complete parts a through c.a. Determine the probability that no errors will be found.
The probability is ___. Round to four decimal places as needed.)

b. Calculate the probability that more than 30 errors will be found.
The probability is ___. (Round to four decimal places as needed.)

c. Find the probability that fewer than 15 errors will be found.
The probability is ___. (Round to four decimal places as needed.)

Answers

The probability that noerrors will be found is 0.

The probability of finding more than 30 errors is 0.0001.

The probability of finding fewer than 15 errors is 0.9452.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The number of errors in a 3,000-word passage follows a Poisson distribution with a mean of 12 errors.

i.e

Since 3,000 is six times 500.

The probability that no errors will be found.

P(X = 0) = $e^(-12)$ x $12^0$ / 0!

= 0.000006

Rounded to four decimal places.

= 0.0000.

The probability of finding more than 30 errors.

P(X > 30) = 1 - P(X ≤ 30)

We can use a Poisson table.

P(X ≤ 30) = 0.9999.

P(X > 30) = 1 - 0.9999

= 0.0001

Rounded to four decimal places.

= 0.0001.

The probability of finding fewer than 15 errors.

P(X < 15) = P(X <= 14)

= ∑(k=0 to 14) $e^(-12)$ x $12^k$ / k!

From the Poissontable.

P(X ≤ 14) = 0.9452

P(X < 15) = P(X ≤ 14)

= 0.9452

Rounded to four decimal places.

= 0.9452.

Thus,

The probability that no errors will be found is 0.

The probability of finding more than 30 errors is 0.0001.

The probability of finding fewer than 15 errors is 0.9452.
