Question

. When rolling two six-sided number cubes, what is the probability of getting a sum of at least 5?

Answer 1

Total number of possible outcomes = 36

Total number of outcomes with the sum at least 5 = 30
{1,4},{1,5},{1,6},{2,3},{2,4},{2,5},{2,6},{3,2},{3,3},{3,4},{3,5},{3,6},{4,1},{4,2},{4,3},{4,4},{4,5},{4,6},{5,1}{5,2},{5,3},{5,4},{5,5},{5,6},{6,1},{6,2},{6,3},{6,4},{6,5},{6,6}

P(Sum of at least 5) = 30/36 = 5/6

Answer: 5/6
