Statistics in Math Homework Help Please!!!!?
I have two questions here I am completely stuck on,,,even if you could just get me started in the right direction it would be great. Popcorn sales in movie theaters break down as 40% plain popcorn and 60% buttered popcorn. While 65% of the plain popcorn is purchased by adults, 80% of the buttered popcorn is purchased by children. (a) (4pts. each part) develop a joint probability table using this information: popcorn sales adults children totals: plain 0.40 buttered 0.60 Totals: To fill in this table, you need to compute the following: 1. the percentage of purchases accounted for by adults buying plain popcorn 2. the percentage of purchases accounted for by children buying plain popcorn 3. the percentage of purchases accounted for by adults buying buttered popcorn 4. the percentage of purchases accounted for by children buying buttered popcorn 5. the percentage of popcorn purchases by adults 6. the percentage of popcorn purchases by children (b) (6 pts) If a child purchases popcorn, what is the probability that it is buttered popcorn? (c) (4 pts) If we let: C represent the event 'child purchases popcorn' B represent the event 'patron purchases buttered popcorn' Then what probability in terms of B and C are you being asked to compute in part b? NEXT QUESTION The table below lists the percentage of late flights, to the nearest percent, among US carriers during January, 2008 (source: Bureau of Transportation Statistics) Use this data to develop a frequency table using six classes: AirTrans 21 Alaska 24 Aloha 6 American 30 American Eagle 28 Atlantic SE 24 Comair 25 Continental 24 Delta 18 Express Jet 25 Frontier 23 Hawaiian 5 Jet Blue 22 Mesa 25 Northwest 27 Pinnacle 26 SkyWest 29 Southwest 21 US Airways 19 United 34

You should not be asking for homework help. You should be trying to work it out yourself or you won't learn.

Nobody is going to read this novel, answer all two dozen questions, and all for the off-chance of winning a ten point BA - which probably wont be appropriately won anyway due to self-voting and incompetent patron selections. You could break this up into a bunch of ten point questions and get each bit explained to you.
