You will add 16 and 24 you will get 40 but your answer choices are 20,30,33 1/3, and 50% so what you will do is take the two numbers closet to 40 which are
33 1/3% and 50 % my teacher always told me if the number is 0 you round down if it is 5 you round up so your best bet would be 33 1/3.
BEST ANSWER:33, 1/3
Answer:
36
Step-by-step explanation:
Answer:
0.0923 = 9.23% probability that four of the patients are still alive after five years.
Step-by-step explanation:
For each patient, there are only two possible outcomes. Either they are still alive after five years, or they are not. The probability of a patient being alive is independent of any other patient, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
Po is an oncologist with seven patients in their care.
This means that 
The probability that a patient will survive five years after being diagnosed with stage three breast cancer is 0.82.
This means that 
What is the probability that four of the patients are still alive after five years?
This is P(X = 4). So


0.0923 = 9.23% probability that four of the patients are still alive after five years.
