Answer:

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.

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
