What is the value of "d" after this line of code has been executed? double d = math. round ( 2.5 + math. random() ); a. 2 b. 3 c. 4 d. 2.5

  3

Explanation:

Math.random() is the function which gives the value greater than or equal to 0.0 and less than 1.0. it gives the double type value.

Math.round is also the function which gives the closest long to the argument.

for example:

Math.round(2.5) it gives 3.

so, Math.random() generate number 0.000 to 0.999

maximum possible value inside the Math.round(2.5+0.999) which is equal to

Math.round(3.499) which gives 3 not 4 when it 3.5 then it gives 4.

therefore, the result is 3
