Three components are randomly sampled, one at a time, from a large lot. As each component is selected, it is tested. If it passes the test, a success (S) occurs; if it fails the test, a failure (F) occurs. Assume that 80% of the components in the lot will succeed in passing the test. Let X represent the number of successes among the three sampled components. a. What are the possible values for X?
b. Find P(X = 3).
c. The event that the first component fails and the next two succeed is denoted by FSS. Find P(FSS)
d. FindP(SFS) and P(SSF).
e. Use the results of parts (c) and (d) to find P(X = 2).
f. Find P(X= 1).
g. Find P(X = 0).
h. Find μ x
