Answer 1

Answer:$P=\frac{2}{5}$

Step-by-step explanation:

Given

A movie theater has 7 seats in the front row  

12 seats in the middle row

11 seats in the back row

Probability first person who enters the theater will be in the middle row

$P=\frac{\text{No. of middle seats}}{\text{total seats}}$

$P=\frac{12}{7+12+11}=\frac{12}{30}$

$P=\frac{2}{5}$
