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

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
