Question

When two dice are rolled, what is the probability the two numbers will have a sum of 5?

Answer 1

$|\Omega|=6^2=36\\ A=\{(1,4),(4,1),(2,3),(3,2)\}\\ |A|=4\\\\ P(A)=\dfrac{4}{36}=\dfrac{1}{9}$

Answer 2

Hope this helps but I think there is a 4/36, or a 1/9 (simplified form of 4/36) possibility of 2 dice having a sum of 5.Because there are 36 possible outcomes when you roll two dice. And there are only 4 possible ways to get a sum of 5 when rolling two dice.Those 4  possible ways are (1,4),(4,1),(2,3),and (3,2).
