3a 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? 2 5 a 2 3 b 4 11 4 15

The probability that the first student who enters the classroom will be assigned a seat in the front row is; Option D; 4/15

We are told;

Number of front row seats = 8 seats

Number of middle row seats = 10 seats

Number of back row seats = 12 seats

Thus;

Total number of seats in classroom = 8 + 10 + 12

>> 30 seats

Now, we want to find the probability that the first student who enters the classroom will be assigned a seat in the front row.

Thus;

P(1st student sits in front row) = 8/30

This can be reduced to get;

P(1st student sits in front row) = 4/15

0.266

Step-by-step explanation:

Total No of seats in class = 8+10+12 = 30

probability that first student will be assigned first row will be: 8/30 = 0.266

because there are 8 front row seats and total seats are 30.
