Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)
Mnenie [13.5K]

Answer:

(1)Minterms complement = XYZ (2) Compliment of Minterms = Σm(0,1, 2 , 4 , 6) (3) (X+Y+Z) (4) Minimized SOP = Z + XY

Manterms = πM

Explanation:

Solution

Recall that:

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

(1) Canonical Disjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as minterms

In Minterm we assign 'I' to each uncomplimented variable and '0' to each complemented/complementary variable

For the given question stated we ave the following:

Minterms = XYZ, XYZ, XYZ, XYZ, XYZ.

(2) Canonical Conjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as maxterms.

In Maxterms we assign '0' to each uncomplimented variable and '1' to each complemented/complementary variable

Compliment of Minterms = Σm(0,1, 2 , 4 , 6)

Maxterms = πM

Note: Kindly find an attached copy of the complete solution to this question below.

natulia [17]

Answer: Geotagging was enabled on her smartphone

Explanation:

The security weakness that is the most likely cause of the security breach is that geotagging was enabled on the vice president's smartphone.

Geotagging, occurs when geographical identification metadata are added to websites, photograph, video, etc. Geotagging can be used to get the location of particular place.

In this case, since geotagging was enabled on her smartphone, it was easy for the attacker to locate her house.
