OK, I thought this would be an easy question, but I got it wrong:
What is the value of the following expression:
Math.round(Math.random() + 2.50001);
Answer: 3
Isn't it possible the value of Math.random() could be 0.99999 ?
If it was then the value of the expression would be 3.5 which would be rounded to 4, no?
Thanks,
Drew

Drew, if this is coming from the RHE mock exam, the answer given is wrong. You are right about round() and random(), so the correct answer to that question would be "impossible to say"
