Suppose approximately 75% of all marketing personnel are extroverts, whereas about 70% of all computer programmers are introverts. (For each answer, enter a number. Round your answers to three decimal places.)

---- At least 5 from marketing departments are extroverts

---- All from marketing departments are extroverts

---------- None from computer programmers are introverts

Step-by-step explanation:

See comment for complete question

The question is an illustration of binomial probability where

--- marketing personnel

--- proportion that are extroverts

Using the complement rule, we have:

So, we have:

So, we have:

Recall that:

--- approximated

--- marketing personnel

--- proportion that are extroverts

So, we have:

---------- computer programmers

--- proportion that are introverts

So, we have:

answer: 40.95

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
