Hi Bob Bundy,
I used the hypergeometric distribution which is for sampling without replacement. The answer is 54 / 143
I agree with your spreadsheet. The question asks for 'at least' 4 females so you need to do 45/143 + 9/143 = 54/143.
thanks. No worries here. I am moving on till I can get help with that problem.
I know the feeling. Just relax, it will all work out or the planet will explode. Either way there is no real sense in worrying.
I do on that one and I did appreciate the joke haha just stressed out over this math. I posted another question as I am stuck yet again. UGH!!!
I don't have to understand everything but when I am receiving a grade on the material, it is nice to know what I am doing and how it works. I honestly could care less about the probability of 3 girls being chosen for a position out of 8 with 7 males and 5 positions with 15 interviews.......
Ah, I remember those. I liked playing with the dial.
Why has the Great Carnac got an old fashioned telephone dial for a necklace? Is it so he can ring for help when the vibes are not good?
Understanding is one of those things that is highly overrated. It is much better to be a good guesser!
3 / 13 is correct. Very good!
