Answer:
d; 4/15
Step-by-step explanation:
there are a total of 8+10+12, or 30 seats, if none of them are filled as in the context of the question. 8/30 are front row seats, and 8/30 can simplify to 4/15 by dividing both the numerator and denominator by 8 and 30's GCF, 2. so the first student has a 4/15 chance of being assigned a seat in the front row.
