What does the following code segment do?

var isSeven = false;

while (isSeven==false)

{

var roll1=Math. floor (Math. random () * 6+1);

var roll2=Math. floor (Math. random () * 6+1);

if (roll1 + roll2 = =7)

{

isSeven = true;

alert (roll1 + "--"+roll2);

}

}

It keeps generating two random numbers of any values until the sum of the two numbers is 7.

It keeps generateing two random numbers between 1 and 6, and adds up the two numbers.

It keeps generating two random numbers between 1 and 6, until the sum of the two numbers is 7.

It keeps generating two random numbers between 1 and 6, then check if the sum of the two numbers is 7.

It keeps generating two random numbers between 1 and 6, until the sum of the two numbers is 7.

Explanation:

isSeven is always false until the sum of roll1 and roll2 is seven.

Math. random () generates a number between 0 and 1 where 1 is exclusive and 0 is inclusive and multiplying it with 6 means that it will generate the number between 0 and 5 and adding 1 means a number between 0 and 6.

Math. floor () is to consider the lower bound integer of the float value for 1.9 it will consider 1 only.
