For each of the following sets of integers, write a single statement that will print a number at random from the set.

a) 2, 4, 6, 8, 10.
b) 3, 5, 7, 9, 11.
c) 6, 10, 14, 18, 22.

a)
```
System.out.print( ( int ) ( ( 1 + Math.random() * 5 ) * 2 ) );
```

b)
```
System.out.print( ( int ) ( ( 1 + Math.random() * 5 ) * 2 + 1 ) );
```

c)
```
System.out.print( ( int ) ( ( Math.random() * 5 ) * 4 + 6 ) );
```
