My cousins and I were playing the game mafia, where everyone gets a card and the person with a jack is a character called mafia but no one knows which card people have until the end of the round. My cousin Teddy got mafia three times in a row. On the fourth time, my cousin Johnny said Teddy might be in the mafia. I said I didn't think so because he had mafia three times already. Johnny said it didn't matter because every time the cards were reshuffled the odds were all the same for everyone and it doesn't matter what people had earlier. I said not completely true. It is rare to get mafia three times in a row and the odds were even less to get mafia four times in a row so therefore the odds were not the same. Who's right in this pathetic fight and can anyone put numbers to it? There were 10 players: 2 mafia, one doctor, one detective, and 6 villagers. It doesn't matter the rules. I just want to know the odds to get mafia 3 times compared to 4 times.

A regular cubic dice can be marked to give 2, 3, or 6 equally likely events. A tetrahedron can give 2 or 4 equally likely events. A Isocahedron can give 2, 4, 5, 10, 20 equally likely events. An octahedron can give 2, 4, 8 equally likely events. Two cubic dice can give 9 equally likely events. What's the smallest combination of such marked regular polyhedral dice that will give 7 equally likely events?

I have a question about taking limits... I never know, when taking the limit as x approachs something like 0 or infinity, how to go about the problem... well obviously I try to rearrange the equations to see if anything cancels, but then I never know whether to try to take the limit as x approaches from either side, or whether to use l'Hopital's rule, or do something completely different... I just get confused...

Is there some kind of checklist of things to try (in order of how you should try them) when evaluating limits like this? By limits like this I really mean limits where you can't directly sub in the number (or other variable) that x approaches.... Thanks!

(and I know l'Hopital's rule is only for indeterminate equations or whatever those are called, I was just giving an example...)

Thanks again! :)

QUESTION:
How would you arrange the steps in order in a continuous, twice differentiable function when finding its inflection point?

THE CHOICES IN RANDOM ORDER:

A = evaluate the function at the points where the second derivate is zero
B = analyze the sign changes of the second derivative
C = find the zeors of the second derivative
D = find the second derivative
E = find the first derivative

Whats the proper order A through E?

Thanks!

Hello can someone help me with this question. Thanks
(Po)/(t+1)
Use your equation from part a to approximate how many years it would take for the population to reach 600. Round to two decimal places if necessary.
so i think it would be like this
600/(t+1)
