Find the number of different distinguishable arrangements that can be formed from the letters in the word APPLICATIONS?
@surjithayer Not sure if I am doing this one right, can you please help?|dw:1391570724981:dw|
total no of letters =12 A's=2 P's=2 I's=2 \[No.of words=\frac{ 12! }{ 2!*2!*2! }\] yes you are doing correct.
=5,98,75,200
Thank you. Can you help with a similar problem? In how many ways can an investor select 5 mutual funds for investment portfolio from a list of 8 funds? I am not sure if this would be 792 or 56? @surjithayer
how you got 792 ?
I'm not sure which formula to use, I got it using this one|dw:1391571437995:dw|
8p5=8*7*6*5*4=?
Oh okay I see now, I had the wrong formula here.. thanks!
a survey of 125 students led to the responses: 87 liked chewing gum, 54 liked coffee, and 24 like both. how many liked coffee but not chewing gum? Do you know what formula for this one?
i am also not sure, i may be wrong ,because i have no book to consult?

Write n(AUB) in place of AUB
only coffee but not gum=54-24=30
i am leaving ,GOOD NIGHT.
