I ended up getting a B on the test. I am glad, I am a senior and this is the last math class I need before I graduate. I finally got what I think is the answer to the problem:
In one roll the expected value is
(1/6)(1 + 2 + 3 + 4 + 5 + 6)
= 21/6 = 3.5
So in 10 rolls...
I am studying for a test tomorrow and this question is on the review sheet and I can't figure it out.
Suppose a fair die is rolled ten times. Find numerical values for the expectations of each of the following random variables.
a) The sum of the numbers in ten rolls;
b) The sum of the...
Hello, I have been stuck on this problem for about a week and a half. I was wondering if there was anyone out there who might understand it and explain it clearly to me.
Suppose a volume of 1000 drops of water contains 2000 bacteria, separate from each other and thoroughly mixed in the...
NEED HELP! with permutation proof
Sorry for any confusion the question I have is:
Show that a permutation with odd order must be an even permutation.
The order of a permutation of a finite set written in disjoint cycle form
is the least common multiple of the lengths of the...
I have been working with the following question for quite awhile:
Show that a permutation with an odd order must be an even
permutation.
I have made some progress, but I am having trouble putting it altogether
to make my proof coherent.
This is what i have so far...
My question is regarding abstract algebra.
Suppost that B is a 10-cycle.
For which integers i between 2 and 10 is
B^(i) also a 10-cycle?
I know that the answer is 3, 7, and 9 I just don't know
how you arrive at these numbers. If...
