Aline, and a point outside the line are in exactly one plane or two planes intersect in a plane. t f → t f t → t f f → f t t → t

 The correct option is

(A) T    F    →     T.

Step-by-step explanation:  We are given to select the truth value statement for the following compound proposition :

A line and a point outside the line are in exactly one plane OR two planes intersect in a plane.

Let us consider that

p : A line and a point outside the line are in exactly one plane

and

q : Two planes intersect in a plane.

We know that the statement p is TRUE and the statement q is FALSE.

Since p and q are connected by OR, so the result will be TRUE iff one of p or q is TRUE.

Therefore, the truth value statement is

p           q              p  or  q

T           F                  T

Thus, option (A) is CORRECT.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
