Answer:
B
Step-by-step explanation:
The chances of the first student walking to school is 7/30.
Without replacement, there are 29 students left. Hence the chance of the second student walking to school is 6/29 of the original 7/30 chance.

It should be 5√3

√25=5 so u bring that out and keep the 3 in because it’s a prime number
