Solutions

Expert Solution

(1)

(a)

Given statement: "If it snows, then we will stay home"

Converse:

If we will stay home, then it snows."

Explanation:

Converse is the switching the hypothesis and conclusion of a conditional statement.

(b)

Given statement: "If it snows, then we will stay home"

Inverse:

If it does not snow, then we will not stay home

Explanation:

Inverse of a conditional statement is when both the hypothesis and conclusion are negated.

(c)

Given statement: "If it snows, then we will stay home"

Contra - positive:

If we will not stay home, then it does not rain.

Explanation:
Contra - positive is switching the hypothesis and conclusion of a conditional statement and negating both.

(d)

Assuming the original statement is true, (c) Contra - positive statement must also be true.

Explanation:

The contra - positive of any true proposition must also be true.

(2)

(a)

The sum of two integers is an integer. : True

(b)

Prime numbers are odd. : False

Counter example: 2 is a prime number. It is even.

(c)

The product of two irrational numbers is irrational. : False

Counter example: is irrational. But is rational number

(d)

The sum of a rational number and an irrational number is irrational. True
