Generate conditional probability question

1 2	makeQA_ConditionalProbability(proportion = NULL, condprob = NULL, type = NULL)

`proportion`	Splits the population into 3 groups with this proportion. Must sum to 1
`condprob`	Gives a conditional probability for each group
`type`	(1, 2). 1: Total probability question 2: Bayes Theorem question

a vector with first element as question, second element as correct answer, and other elements as other answer choices.

makeQA_ConditionalProbability(type = 2)
 "A company buys resistors from vendor companies A, B, and C.
 30% come from company A  40% come from comapny B, and 30% come
 from company C.  If a resistor comes from company A, there is a
 67% chance that it is within tolerance.  If a resistor comes from
 company B, there is a 57% chance that it is within tolerance.
 If a resistor comes from company C, there is a 82% chance that
 it is within tolerance.  If a randomly selected resistor is
 within tolerance, what is the probability it came from company A?"
