What is the value of “d” in the following Java code snippet?
double d = Math.round ( 2.5 + Math.random() );
a) 2
b) 3
c) 4
d) 2.5

Answer: b
Explanation: The Math.random() method returns a number greater than or equal to 0 and less than 1. so 2.5 will be greater than or equal to 2.5 and less than 3.5, we can be sure that Math.round() will round that number to 3.
