A classroom is arranged with 8 seats in the front row, 10 seats in the middle row, and 12 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom. What is the probability that the first student who enters the classroom will be assigned a seat in the front row?

4/15

Step-by-step explanation:

Given 8 seats in the front row

10 seats in the middle row and 12 seats in the back row

Total number of seats = 8 + 10 + 12

= 30

Probility that the firstborn student who enters the class is assigned a seat in the first row is

No. of seats in the first row/ total number of seats in the classroom

That’s 8/30

4/15

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

the probability that a bird is green (.30) is true
