prohojiy [21]

As in each table can seat 8 people and the probability you need to find is about the first person you can ignore this data.

P(maple)=\frac{#maple\text{ }tables}{#total\text{ }tables}

#maple tables: 9

# total tables: 9 +10 +5 +7=31

P(maple)=\frac{9}{31}Then, the probability that the first person to enter the room will be randomly seated at a maple table is 9/31
