Probability- Union and Intersection

I need help with an intersection problem. I have listed the values and the question below. If someone could please explain how to do this problem I would be very, very happy!

P(A)= 0.6
P(B)= 0.55
P(A n B)= 0.35

Find: P(A n (not B))

Re: Probability word begins with O, ends with R

So...

If you can arrange all of the letters in "POKER" in 120 ways, and
you can arrange letters "PKE" (with O and R on the outside) in 6 ways,
would it be 6/120?

Probability word begins with O, ends with R

Can someone show me how to do this problem? I think that it is conditional probability, but I am unsure how to set up the problem. Thanks... If the letters in the word "POKER" are rearranged, what is the probability that the word will begin with the letter "O" and end with the le...

Re: Factorials: (4n + 1)! / (4n - 1)!

So then... the denominator would be: 1x2x3x(4n-2)x(4n-1)
And all of that would cancel out with the numerator, leaving (4n)x(4n+1), which is (16(n^2))+4n!

Thank you sooooo much! :clap:
