Question

a classroom is arranged with eight seats in the front row 10 seats in the middle row 12 seats in the back room the teacher randomly assigned seats to students as they enter the classroom what is the probability of the first student who enters the classroom will be assigned a seat in front row

Answer 1

Answer: $\frac{4}{15}$

Step-by-step explanation:

The number of seats in the first row= 8

Total number of seats in the classroom= $8+10+12=30$

The probability of the first student who enters the classroom will be assigned a seat in front row is given by:-

$P=\frac{\text{Number of seats in first row}}{\text{Total seats}}\\\Rightarrow\ P=\frac{8}{30}=\frac{4}{15}$

Therefore, the  probability of the first student who enters the classroom will be assigned a seat in front row is $\frac{4}{15}$.
