Stocks listed on the New York Stock Exchange follows a non-normal distribution with mean
µ = 11.2 percent and a standard deviation of σ = 8.4 percent.

That was given to me and I have to answer whether or not I can find the probability that a single stock has an annual return less than 34 percent? Explain why or why not.

I'm really struggling with this class and can't seem to figure out where to begin in answering this question.

Jake runs the concession stand for a Chicago area minor league baseball team. He knows that hot dog sales are normally distributed with an average of 600 hot dogs per day and a standard deviation of 50.
Jake doesn't want to run out of hot dogs. If he can order each day how many hot dogs should he order so that the probability of running out is less than 2%?

b. what is the probability that no more than 50 hot dogs will be left over at the end of a day?

c. what is the probability that more than 100 hot dogs will be left over at the end of a day

Wed, 22 Oct 2014 00:21:41 GMTI have 1,2,3,4,5,6,7,8,9,10,11,12 teams. Only 8/12 teams make it to the playoffs.

What is the probability that 3,4,5,8,9,10 are part of the 8 teams that make it to the playoffs? Given each team has 1/12 chance of making it.

I solved it like this, (8 choose 6) /(12 choose 8) = 0.056. Is this correct?
