1. Consider n flips of a fair coin. Calculate the probability: a. n/2 < -Total number of heads b. 5000 > total #heads c. n/2 < total #heads < 5n/8 d. n < total #heads. WHERE n = 8992 2. Consider the shopping problem Markov transition matrix .5 | .5 ----------------- .75 -...

Thanks wlkhoo, that's the question I was aimning for, thanks everyone for the help. So can it be solve for any number of colleges or would it have to be a fix number?

Thanks for the help, can you elaborate more on the 2nd part?

Hello all, I have a question about a problem given in class. Here is the quetion: There are 3 college counselors( A, B, C). The counselors will pick a college for the student. 1. A is correct 80% of the time. 2. B is correct 10% of the time. 3. C choice depends on A and B. If A and...

Thanks everyone for helping me out with this question, now I just have one more question, what is the equation for combination. I have an idea what it is, I just need to confirm it. Thanks for the help.

Thanks for posting and helping me with my question. I understand now for question a and b, but for c I have to look into binominal expansion, I have to look into it a little more. Thanks again.

Thanks for the post. This is for question a, so the probability for different outcomes for an unfair coin would not matter if it was a fair coin, the probability would be the same as a fair coin? This is for question b, fair or unfair coin, the # of outcome of heads would not matter? I am...

Probability (unfair coin) Hello everyone, I need a little help with this problem I have. Question: A unfair coin is flipped 3 times. probability of Head = 2(probability of a tail) a. How many different outcomes are there? b. How many different outcomes for the # of heads? c. Is...
