Question

The probability is p = 0.80 that a patient with a certain disease will be successfully treated with a new medical
treatment. Suppose that the treatment is used on 40 patients. What is the mean number of patients who are
successfully treated?​

Answer 1

Answer:

probability=0.8

Total no. of patients=40

Therefore no. of patients who are successfully treated=x

0.8=x/40

x=32

Answer 2

Answer:

Number of patient who are successfully treated are 32

Step-by-step explanation:

Given:

Probability that successfully treated = 0.80

Total no. of patient= 40

Let number of patient who are successfully treated be x

As we know that,

Probability = favourable outcome / total outcome

    0.80 = x / 40

        x= 40 × 0.80

           x= 32
