I think it is (0,b). Though I might be mistaken. After you plug in the numbers, it should be -3a+3a/2 and b+b/2. Once simplified that is 0/2 and 2b/2. 0/2 is just 0 and 2/2 is 1 leaving b. So the answer is (0,b).

Po is an oncologist with seven patients in their care. the probability that a patient will survive five years after being diagno
alekssr [168]

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.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

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

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Po is an oncologist with seven patients in their care.

This means that n = 7

The probability that a patient will survive five years after being diagnosed with stage three breast cancer is 0.82.

This means that p = 0.82

What is the probability that four of the patients are still alive after five years?

This is P(X = 4). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 4) = C_{7,4}.(0.82)^{4}.(0.18)^{3} = 0.0923

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