A​ single, fair​ 6-sided die is tossed. Find the odds in favor of rolling a 1 or 3.

Answer 1

Probability = number of events/the number of possible outcomes

In this problem this translates to:

(rolling a 1 + rolling a 3)/(total possible rolls of the dice)

Keep in mind there are 6 sides on the dice. There is one 1 and one 3

(1+1)/(6) = 2/6 = 1/3
