Answer: 1/6
======================================================
Step-by-step explanation:
E = event space = {1}
The event space is the set of things we want to happen. There's only one outcome and it's the "1" (since it's smaller than 2)
S = sample space = {1,2,3,4,5,6}
There are 6 items in the sample space.
Divide the two counts to get the fraction 1/6 which is the probability of rolling a result less than 2. In other words, the probability of landing on "1" is 1/6 since there's one face with that label out of 6 faces total.
Side note: 1/6 = 0.1667 = 16.67% approximately
