The code segment below is intended to randomly print one of the values 2, 4, 6, or 8 with equal probability.
int val = /* missing code */ ;
val *= 2;
System. out. print(val);
Which of the following can be used to replace /* missing code */ so that the code segment works as intended?
a. Math. random() * 4 + 1
b. Math. random() * 8
c. (int) (Math. random() * 4)
d. (int) (Math. random() * 4 + 1)
e. (int) (Math. random() * 8 + 1)

D. (int) (Math.random() * 4 + 1)

Explanation:

The first two options (A and B) will give a compiler error incompactible types since the Math.random() functions returns a double and val has been declared as an int. To overcome this, a type casting to integer is carried out. Option D (int) (Math.random() * 4 + 1)  will return a value after been casted to an int of 1,2,3,4 which when this line val *= 2; is executed gives the expected output of  2,4,6 or 8.
