p(a)=.66 p(b)=.31 (a upside down u b)=.21
b. p(a upside down u b)
c. P(a upside down u b)c)
a. p(a/b) = P( a n b)/p(a) = 0.21/0.66 =b. p(a upside down u b) is already given, i think you typed it wrong here.
B. P(a u b)
C. P(a u b)c)
sorry but you do not even appreciate the help you are getting by simply besting an answer. I don't see any point in helping you :(
Are we getting .32 for part A!
It won't cost you anything to select and answer as best, but you still don't do it..Sorry but I cannot help you, if you dont appreciate my help.
I'm sorry u feel that way.....I do appreciate your help...I'm new to this cite....it will take time for me me to understand what I need to do when choosing a best answer....thank you
I will select.....now that I know that's what I need to do...thanks
Please do it...
B. P(a u b) = P(a) + p(b) - p(a n b) = .66 +.31 - .21 = .76
Thank you for part a and b......no problem on c....you have been a great help
can you please check this one as well...
c. P(AUB)c=1-P(AUB)= 1 - .76 = 0.24
