From a box containing 60 standard and 40 substandard article, two articles are chosen at random. What is the probability that one of them is standard and the other substandard? A.16/33 B.8/33 Answer is 16/33. My doubt is as in question it is not given simultaneously. How to know random means simultaneously or one by one? Or it is explicitly they give one after one.
