Answer:

P(A\ and\ B) = \frac{3}{7}

Step-by-step explanation:

<em>Your question is not well presented; (See Attachment for complete details)</em>

<em></em>

Required

Find P(A n B)

where

A = Event that the place is a city

B = Event that the place is in North

The first step is to get the sample space;

Let S represent the sample space;

S = \{India,\ Tokyo,\ Houston,\ Peru,\ New York,\ Tijuana,\ Canada \}

n(S) = 7

The next is to list events A and B

A = City

A = \{Tokyo,\ Houston,\ New York,\ Tijuana\}

B = North America

B = \{Houston,\ New York,\ Tijuana,\ Canada\}

The next is to list common elements in A and B

A\ n\ B = \{Houston,\ New York,\ Tijuana\}

n(A\ and\ B) = 3

The probability of A and B is calculated as follows;

P(A\ and\ B) = \frac{n(A\ and\ B)}{n(S)}

Substitute n(A\ and\ B) = 3 and n(S) = 7 in the expression above

P(A\ and\ B) = \frac{3}{7}

(3)-2<br> Evaluate exponent
olga nikolaevna [1]

Answer:

3^{-2} = \dfrac{1}{9}

Step-by-step explanation:

Definition of negative exponent:

a^{-n} = \dfrac{1}{a^n}

In our case, a = 3 and -n = -2.

3^{-2} = \dfrac{1}{3^2}

Now we just evaluate the power in the denominator.

3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{9}
