ill post it one sec

P(A|B) is a method of expressing conditional probability where in this case it means the probability of event A if event B has ocurred

10. dan815

11. anonymous

so would that be p(a)

12. dan815

P(A|B) where A is number of Twitter users And B is the year

13. anonymous

ohh and would the net one be for instagram?

14. anonymous

or would it be twitter again but reversed

15. dan815

no you have to invert the equinox

16. anonymous

so 2010?

17. dan815

thats right

18. dan815

P(A|B) means Probablity of A given B

19. anonymous

oh so how would i write that

20. dan815

so say for P(twitter|2015), this can be interpreted as how many twitter users out of all the other users in the year 2015,

21. dan815

which is 270 million/ 570 million

22. dan815

23. dan815

33. anonymous

dude i wrote that lol...

34. dan815

see how these 3 numbers get used the column and row relationship

35. anonymous

yes

36. dan815

for P(A}B) vs P(B|A)

37. dan815

thats all u need to talk about

38. dan815

you can do a couple of those for your data given to compare

39. dan815

you would talk about how for P(A|B) is focused on a ROW and P(B|A) is focused on a COLUMN

40. anonymous

ok thanks and what about Compare P(A∩B) with P(A∪B), and explain what each probability means in the context of the situation and data you collected.

41. dan815

P(AuB)= P(A)+P(B) - P(AnB)

42. dan815

upside down u is intersect and u is union

43. anonymous

so can you write that in numbers LOL

44. dan815

|dw:1436511330949:dw|
