B.1/5
C.2/3
D.5/6

Respuesta :

Answer:

D. 5/6

I just took it, it's correct.

Answer:

Option A is correct.

Step-by-step explanation:

We are given with Total waiting time of a bus = 30 minutes

also given that we arrive at bus stand and have to wait for 5 minutes.

[tex]Probability=\frac{Number\:of\:favorable\:outcome}{Number\:of\:Total\:Outcome}[/tex]

So, [tex]Probability=\frac{5}{30}=\frac{1}{5}[/tex]

Therefore, Option A is correct
