Which of the following illustrates the truth value of the given statements?
Ierofanga [76]

Answer:

FT\rightarrow T

Step-by-step explanation:

If p and q are two statements, then you can use the following table to find the value of p\vee q:

\begin{array}{ccccc}p&|&q&|&p\vee q\\ \\T&|&T&|&T\\T&|&F&|&T\\F&|&T&|&T\\F&|&F&|&F\end{array}

If

p: 7 is an even number  - is false, because 7 is not an even number (F)

q: 3 is the square root of 9 - true, because 3 is the square root of 9 (T),

then according to the above table, p\vee q is true.

Correct option

FT\rightarrow T
