St1: least prob is 6/10 * 5/9 = 1/3 and max prob is 1.: INSUFF

in this particular step, I always get confused.

I dont know what rule to apply to get probability of selecting 2 women.

Choice 1:

Like you have done probablility = 6/10 * 5/9

Choice 2: (what I did when trying to solve this problem on my own!)

Least Probability = 1/6*1/5

(out of 6 women, probability of selecting the first is 1/6. now that one is selected, the probability of selecting the next is 1 out of the 5 remaining).

what i would like to know is why you have taken choice 1 and not choice 2. is there a particular formula / method that indicates when to use what pls ?

any help on this would be highly appreciated.

thanks.
