A cancer researcher wants to test a new combination of chemotherapy and radiation on skin tumors in laboratory mice. The researcher administers the treatment to each of four laboratory mice having the type of skin tumor under study. After a week of treatment, the researcher records failure or success for each mouse, depending on whether or not skin tumor cells are observed on the animal. Let S represent the cancer disappears and F represents the cancer did not disappear. The sample space events are as follows: SSSS SSSF SSFF SFFF FFFF SSFS SFFS FSFF SFSS FFSS FFSF FSSS SFSF FFFS SFFS FSF

Suppose that the treatment combination has no effect on the skin tumors. However, there is a .1
Since the mice are independent calculate the probability for each of the events above. Note that each

Column 4=
Column 5=
Kindly help to explain. I want to understand the procedure and how the answeres were derived. Thank you!
Binomial distribution is used to when we have n number of independent trials and probability of success is same for each trial.
