Hi, in this question in the a part we have to write the contrapositive of the statement.
00:18
So the contrapositive of the statement will be a and b are not even.
00:28
Then a plus b is not even.
00:37
In the b part we have to write the converse.
00:42
So the converse of the statement will be and this implies that if, if, a and b are even then a plus b is even.
01:02
In the c part we have to write the negation of the statement.
01:08
This implies if a plus b is even then a and b are not even.
01:25
In the d part the given statement is true and we have to find.
01:29
Prove that is a plus b is even then a b are equal.
01:34
Now we can say that suppose the sum of a plus b is 2 into x plus y.
01:46
That is an even numbers because it's multiplied by even.
01:50
2 into x plus 2 into y...
