i got 27over 125 but its not one of the answers

nipunmalhotra93 · Answer

I think it is exactly 1. Then the answer is B. If it is atleast 1, then it is 117/125 which is none of the options.

For atleast 1, just fine the probability of drawing red all three times and subtract from 1.

nipunmalhotra93 · Answer

The question says exactly 1 imo.
