Two different antibiotics can be used to treat an infection. treatment with antibiotic 1 is known to be successful 80% of the time. this treatment costs $80. antibiotic 2 is successful 90% of the time and costs $100. the two treatment plans are: plan a: treat with antibiotic 1. if not effective, treat with antibiotic 2. plan b: treat with antibiotic 2. if not effective, treat with antibiotic 1. based on the data provided, what is the probability that a patient treated under plan a will be successfully treated?
a. 0.98
b. 0.72
c. 0.80
d. 0.90

Option A

A. 0.98

Step-by-step explanation:

Plan A consists of:

Plan A: treat with antibiotics 1. If not effective, treat with antibiotics 2

Antibiotic 1 has a probability P (1) of 0.8 to be effective

Antibiotic 2 has a probability P (2) of 0.9 to be effective.

For a patient to be treated successfully with plan A it can happen that:

The antibiotic 1 works, or that the antibiotic 1 does not work but the 2 antibiotic if it works.

So the probability that plan A works is:

i need a picture or some numbers

step-by-step explanation:

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
