3 students are randomly selected with replacement from this data set, and we are interested in the probability that a student attends XUniversity. If you were to create a probability distribution, i.e. P(k=0), P(k=1), P(k=2), P(k=3), what would the standard deviation be of this distribution? (Note: You do NOT need to calculate all of the probabilities in the distribution to find the mean and variance.)

NOTE : The data for X university as follows :
Frequency= 37
Percent=61.7
Valid Percent=61.7
Cumulative Percent=61.7

Thanks :)

Read this first: Expectations for the Homework Help board
Do not simply retype or paste a question from your book or study material

We won't do your homework questions for you.
You were given the assignment for you to learn.

If you come up with your own answer and post it for us to critique that is within reason.

If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
But this is your assignment, so show us you have at least attempted to complete it on your own.

Thank you.
