Identity Probability Distributions. In this exercise, determine whether a probability distribution is given. In the case where a probability distribution is not described, identify the requirements that are not satisfied. In the case where a probability distribution is described, find its means and standard deviation.
Mortality Study For a group of four men, the probability distribution for the number x who live through the next year is as given in the accompanying table.
x P(x)
0 0.0000
1 0.0001
2 0.0006
3 0.0387
4 0.9606
