Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~PAP Q~QvQ

NNADVOKAT [17]

Answer:

The statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$ is a tautology.

Step-by-step explanation:

We have the following statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The simple statements from the statement given are:

$\lnot P$ , $\lnot Q$ , $\lnot P \land P$ , $\lnot P \land P \rightarrow Q$ , and $\lnot Q \lor Q$ with these you can construct the following truth table.

A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.

The last column contains only true values. Therefore, the statement is a tautology.

At a local college, of the male students are smokers and are non-smokers. Of the female students, are smokers and are non-smoker

natima [27]

Answer: Our required probability is 0.88.

Step-by-step explanation:

Since we have given that

Number of male students are smokers = 10

Number of male students are non smokers = 490

total number of male students = 500

Number of female students are smokers = 40

Number of female students are non smokers = 363

Total number of female students = 403

Probability that both are non smokers is given by

$P(Non-smoker\ male)\times P(Non-smoker\ female)\\\\=\dfrac{490}{500}\times \dfrac{363}{403}\\\\=0.98\times 0.9\\\\=0.88$

Hence, our required probability is 0.88.
