What is a dis junction and an example of one? (math)

A disjunction is a compound statement formed by joining two statements with the connector. A disjunction is false if and only if both statements are false; otherwise it is true.

Example 3:

Given:r: x is divisible by 2.

s: x is divisible by 3.

Problem:What are the truth values of rs?

Solution: Each statement given in this example represents an open sentence, so the truth value of rs will depend on the replacement values of x as shown below.

If x = 6, then r is true, and s is true. The disjunction rs is true.

If x = 8, then r is true, and s is false. The disjunction rs is true.

If x = 15, then r is false, and s is true. The disjunction rs is true.

If x = 11, then r is false, and s is false. The disjunction rs is false.

what is the original number? you forgot to add it.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
