selected, what is the probability of observing, at most, one patient who will be cured of breast cancer?

A• (20)/1 (0-20)^1 (0.80)^19

B. 1-(20)/1 (.20)'(0.230)

C. (20)/0( .80)^20+(20/1)(.20)^1(.80)^19

D • (20)/0 (.80)^20

E. 1-(20/0)(.80)^20

Answer:

It's actually C

Step-by-step explanation:

don't forget about the probability of 0 too

you have to add the two probability formulas

The probability of observing, at most, one patient who will be cured of breast Cancer will be P = (20 / q²⁰) + 20 / (0.20 x 0.80¹⁹). Then the correct option is C.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

A new drug on the market is known to cure 20% of patients with breast cancer.

p = 0.20

q = 1 – 0.20

q = 0.80

If a group of 20 patients is randomly selected.

The probability of observing, at most, one patient who will be cured of breast Cancer will be

P = (20 / q²⁰) + 20 / (0.20 x 0.80¹⁹)

Then the correct option is C.
