Answer:
Step-by-step explanation:
This question is somewhat lacking in detail or the information is not properly delivered/presented, this can be seen in the two statements bellow
1. 14 of the applicants were successful
2. Of the successful applicants, 15 couldn't make all the training sessions.
The two statements cannot hold true especially statements two, because if 14 volunteers were successful, then 15 volunteers cannot be selected from 14.
