Does that mean my answer is wrong then? Shoot. I'll have to se what I did wrong.
The probability that the three cards are not all red (assuming that there are 26 red cards in the deck and each card is not put back in the deck after it has been drawn) is approximately 0.8824 or 88.24%.
Thank you so much! You guys are the best. See you again in a month or so ;)
Thank you so much! I'm pretty good at understanding chemistry, but I can't do math for the life of me.
Edit: In your answer you listed the total mass as 220 grams instead of 210. Is that correct?
I don't know a whole lot about statistics, but maybe this chart can help. It's what I used to determine my answer.
A seems like the most likely answer to me.
The 80 people surveyed are the sample and statistic, which is used to create an estimated measurement for the whole population.
I'm seeing about 29% to 30% of respondants paying more than 700 a month.
Thanks!
