university business students had cheated in someway. This compares to
another study showing that 53% of all univeristy students had cheated.
Suppose that at a particular university, business students are 20% of the
studnets enrolled.
a)what is the probability student chosen at random is a non business

I am not sure how to solve this since there are 2 values on the right side of the equation. Please help. I was only shown how to do this with one value on the right side.

(a) Locate and classify the singularities (giving the order of any poles) of the function:

f(z)= z/(1-e^z)

(b)Let f(z) = zsinh(1/(z+1))
(i) Find the Laurent series of f about -1 giving the general term of the series for odd and even powers of (z+1)
(ii) Write down a punctured open disk D, containing a circle C={z:|z+1|=1}, on which f is represented by this series
(iii) State the nature of th singularity of f at -1
(iv) Evaluate
integral zsinh (1/(z+1))dz where C = {z:|z+1|=1}
(c) Find the laurent series about 0 for the function

f(z)= 7z/((2z+1)(z-3)) on the set {z:|z|>3}, giving the general term of the series

I'm trying to build a wind tunnel to do some testing in, and I'm having trouble figuring how to determine this so I know the proper fan to purchase for this. I don't have an anemometer yet, but that will only really be needed during testing to monitor the speeds. I just need to figure out how big of a fan (CFM requirements) I'm gonna need to achieve these high wind speeds in the tunnel without having to go through a dozen fans using trial and error. Any help with this would be greatly appreciated. Thanks!

Sorry everyone...
I posted the wrong question...

It should be...

1/2 + 2/4 - 5/6
--------------------
3/2 x 1/3 divided by 5/10

That is only one question...
