Answer:

B

Step-by-step explanation:

Recall the product property of exponents, where:

x^a\cdot x^b=x^{a+b}

In our expression, x is 3, a is -8, and b is 4. Thus:

3^{-8}\cdot 3^{4}=3^{-8+4}

Add in the exponent.

=3^{-4}

So, our answer is B.

And we're done!

The probability that you looking for is sum of probability of getting someone in the 18-27age (74 persones) and probability to getting someone who refused (36 and 19 persones) - probability of getting some of 18-27 age who refused (36 persons).

The probability is:

P(a or b)= p(a)+p(b)-p(a&b)=74/371+(36+19)/371-36/371=0,199+0,148-0,097=0,250
