Query about Question 1 from "Timed Quant Section (15 Questions, Hard) #13" [46]

write your quesShouldn’t this question specify that the two events are independent?
The solution calculates the probability that both students pass as 0.45×0.55, which assumes that their test results are independent. However, the question does not explicitly state that they are independent. Without this assumption, I don’t think the relationship between the two quantities can be determined. Could you please clarify?tion here…

It is reasonable to assume that there is no collusion.

@Shweta and @gregmat what do you think?

I edited it to be clearer
