Answer 1

Answer:
`P=(2)/(5)`

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=(12)/(7+12+11)=(12)/(30)`

`P=(2)/(5)`
