yes, if you have only two equations, you can divide left and right sides \[ \frac{a_1}{a_2} = \frac{k b_1}{k b_2} = \frac{b_1}{b_2} \]

consider rolling a 6 sided die, what is the probability that it takes at least two rolls for the first 5 to be observed? Attempt: (5/6)(1/6) = 5/36 but that's wrong. My thoughts: first roll is 1,2,3,4,6 and second roll needs to be 5, hence my attempt. Should I be using combinatorics here or am I misreading the prompt?
