Can someone please help me understand congruent things... I'm supposed to have a quiz on it soon but I never even had a lesson on it and the lesson I'm doing now doesn't say how I'm supposed to figure it out. &lt <--- that's a link to one of the questions I have on the assignment before the quiz

What is the probability of throwing several dice with sum equal to 6 (six)? show the ways of possibilities for sum 6 (as the numerator) and the ways of throwing n dices for n = 1, 2, 3, 4 or 5 as denominator for all the questions to earn full credits. (a)throw one die, (b) throw two dice, (c) throw three dice (d) throw 4 dice, (e) throw 5 dice
