Anew drug on the market is known to cure 20% of patients with breast cancer. if a group of 20 patients is randomly
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(.80)^19
d • (20)/0 (.80)^20
e. 1-(20/)^20
01-(20)10.2010

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

rounding to the nearest thousandth would be 452,000

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
