Explanation:
Logical operators:
'and' indicates that the statement is true if both conditions are true.
'or' indicates that the statement is true if one or both conditions are true.
Given that a = 1 and b = 10:
The first statement is false (1×10 <= 1 is false, 1 >= 10 is also false)
The second statement is false (1>10 is false, a does not equal b)
The third statement is false (a does not equal b)
None of these statements are true.
Hope this helps :)
