    Odds of both = Odds of one * Odds of the other

    yes, thats right 3/6. because it said LESS than 4, so you have only 3 numbers less than 4. Okay, now what are the odds that you will land a heads on a toss of a coin?

    No, like polpak said, odds of both occurring = odds of one* odds of other.

    so you multiply 1/2 and 1/2
