since there are two numbers lower than 3 then its 2/6 which is 1/3 of 30
1/3 *30=10

< 3 = 1 or 2. 1 or 2 are 2/6 or 1/3 of the possible dice rolls. In theory, the probability that either 1 or 2 comes up is 1/3 of the time, or ten of those 30 times.

there are to numbers less than three so 2/6 times or 1 out of every three rolls, 30 x (1/3) = 10
10 times
