Hi;

These questions are more interesting if you allow different combinations of solutions for theta in the same expression, e.g. add/subtract a different multiple of pi for each occurrence of theta. There are then multiple answers

I think Solvitur means the paradox that an immortal being can do all of:
1. Make a promise
2. Never fulfill that promise, and
3. Never break that promise either.

Oh I see. You wanted the population sd

Hi,

If you were to take:

And divide it by two, you would get:

This is false for any number.
I think there is something arbitrary about adding zeroes as placeholders, something relating to the point that zetafunc has been making

Hi zetafunc,

I basically just parroted a chain of reasoning I have seen before. What goes wrong with this argument? smile

Hint ... question 1 answer is the denominator of question 2

Hint two ... The 0.02 and 0.05 bits are the probabilities I meant, not the whole thing

Hello!

1. It is like the other problem with ice creams. You need to multiply each probability by the percentage you pick that supplier

2. Once you get your two products from question one, you need to find out Supplier A's product as a percentage of the total

3. Two parts being defective is the probability of one being defective squared. I guess it is a bit like question one, except you are multiplying the probabilities twice


Nehushtan,

Sorry if I gave too much away hmm
