According to government data, 15% of employed women have never been married. Take a random sample of employed women and observe their marital status.
a. Is x normal, binomial, or geometric? (I don't understand the difference, if someone could explain this to me I would be so grateful!!)
b. If 8 employed women are selected at random, what is the probability that 2 or fewer have never been married?
c. If 8 employed women are selected at random, what are the mean and standard deviation?
I know this should be simple but math is really hard for me to understand, if anyone could explain any part of this to me I would really really appreciate it!!:)
