Answer:

P(algebra, then statistics) = 7/80

Step-by-step explanation:

The total number of books is 7 + 8 + 5 = 20.

1. P(algebra, then statistics)

The probability that the first book is an algebra book is 7/20.

Carlos then replaces the book, so the total is still 20.

The probability that the second book is a statistics book is 5/20.

Therefore, the total probability is:

P(algebra, then statistics) = 7/20 × 5/20

P(algebra, then statistics) = 7/80

snow_lady [41]
The correct answer is A) yes, the sum of each pair is greater than the third.

The triangle inequality theorem states that the sum of any two sides of a triangle is longer than the third side. This is true for these numbers, so this does form a triangle.
