    Combinations and probability distributions

    Can someone please help with the method of how to solve this problem... Question: Three balls are thrown at random into 5 bowls so that each ball has the same chance of going into any bowl independently of wherever the other 2 balls fall. Determine the probability distribution of the...

    Probability proof - what formulas are needed here?

    If events A and B are in the same sample space: . Proove that if P(A I B') > P(A) then P(B I A) < P(B) (where B' is the Probability of A given not B) . Proove that if P(A I B) = P(A) then P(B I A) = P(B) do we assume independence here so that P(A I B) = [P(A)*P(B)]/ P(B) = P(A)...

    Implicit differentiation and chain rule-

    Sorry it seems that attachments do not upload: Here is the Question: Suppose R = R(q,p) = e^(q+p), where p = p(q) is defined through the equation q^2*p+p^2*q+qp = 3 Letn r(q) = R(q,p(q)). Use the chain rule to calculate the derivative dr/dq at the point q=1. Can you please tell...

    Writing a function as an exponent - please clarify

    Can someone please clarify: If i wish to write2^(√2) as an exponent am I correct in thinking this will be written as: exp√2(ln2) ? Thanks

    Math/ Economic brain teaser - due to the credit crisis

    Ok, this question is a bit tricky, but it is wise to first make certain distinctions. There are loans available and there are investment projects. People borrow (i.e. take out a loan) to finance their spending now. They invest in a project (with the quality of that project varying over a...

    Math/ Economic brain teaser - due to the credit crisis

    Supply: S=2000*ibar Demand: Those who enter the loan market q: the quality of the investment project - this lies on a uniform distribution on scale [1,2] this is what you can use to determine who enters the market, as for example if i = 0, you know all 2000 people will enter the market...

    Math/ Economic brain teaser - due to the credit crisis

    Can anyone sense a way to solve this. It would be great help to see your reasoning behind your assumptions. As a result of the credit crisis there are many asymetries in the loan market as a reult this set of question have arisen: Information - take this as true There are two types of...

    Interpeting data figures - its rather simple but not soo simple

    Can Someone please tell me how I can interpret the skewness of a distribution using quartiles. I know that if Q2 – Q1 > Q3 – Q2 : Negative skew and if Q3 – Q2 > Q2 – Q1: Positive Skew and if Q2 –Q1 = Q3 – Q1: Symmetrical data dispersion What I really need to know is how to use the above to...

    MSE and Estimators for Random Samples

    Erm Ok, so you are suggesting that considering random variables, the expected value of an unbiased estimator (used in a sample to estimate the true population parameter, such as the unknown mean or variance etc) has an expected value equal to its true population parameter? So with what you...
