Answer: 33.3%

Step-by-step explanation:

From the given table, the number of books which is a nonfiction paperback =23

The total number of books = 69

Then the probability that a randomly selected book is a nonfiction paperback is given by :-

\text{P( nonfiction paperback)}=\frac{23}{69}=0.33333....

In percent, \text{P( nonfiction paperback)}=0.33333.....\times33.333\%\approx=33.3\%

Hence, the probability that a randomly selected book is a nonfiction paperback is 33.3%

We have given the 2 by 2 frequency table.

The probability that a randomly selected book is a nonfiction paperback =

(Number of nonfiction paperback books) / Total number of books

= 23 / 69

= 0.3333

The percentage of nonfiction paperback books is 33.33%

Two integers will be randomly selected from the sets above, one integer from set A and one integer from set B. What is the proba
Fittoniya [83]

Question:

A = {2, 3, 4, 5}

B = {4, 5, 6, 7, 8}

Two integers will be randomly selected from the sets above, one integer from set A and one integer from set B. What is the probability that the sum of the two integers will equal 9?

A. 0.15

B. 0.20

C. 0.25

D. 0.30

E. 0.33

Answer:

Option B: 0.20 is the probability of the sum of the two integers.

Explanation:

The sample space for selecting 2 numbers is given by

4\times 5 = 20

We need to determine the probability that the sum of two integers will be equal to 9.

Hence, we need to add the two integers from the sets A and B such that their sum will be equal to 9.

Hence, the sets are (2,7),(3,6),(4,5),(5,4)

Thus, the total number of sets whose sum is equal to 9 = 4

The probability that the sum of the two integers will equal 9 is given by

P=\frac{4}{20}

P=\frac{1}{5}

P=0.20

Thus, the probability that the sum of the two integers will equal 9 is 0.20

Hence, Option B is the correct answer.
