Answer:
33%
Step-by-step explanation:
There were 3 students total who were assigned, this would be your denominator (n/3). If only 2 showed up, that would mean that 2/3 of those assigned attention showed up, so 67%. However, it asks for what percentage didn't, so you'd do 3/3 - 2/3, which is 1/3 (You subtract from 3/3 because there was a total of 3 assigned.) 1/3 into a percentage is 33%
