How many possible pairs of values can you get when you toss 2 dice simultaneously?
If [i]a[/i] is the number on top of the first dice, and [i]b[/i] the number on top of the second one, we have 36 possibilities for ([i]a[/i], [i]b[/i]).[br][br]In fact you can apply the [i]multiplication principle[/i]: since you have 6 possibilities for [i]a[/i], and 6 for [i]b[/i], the number of joint outcomes ([i]a[/i],[i]b[/i]) is 6 times 6, that is 36.
