What is the value of "d" after this line of code has been executed? double d = Math.round ( 2.5 + Math.random() ); Answer: 3

The Math.random() method returns a number greater than or equal to 0 and less than 1 . Since we can then be sure that the sum of that number and 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. So Option B is the answer.
